Rock Cakes by Hagrid

rock cakes by hagridHarry Potter is celebrating a birthday shortly, which is the only excuse we need to bust out our hats and robes and do something Potter. You might recall our Wand Works event, which included some awesome Flourish & Blotts giveaways. Well, when Katie and I were researching said giveaways, we stumbled across The Unofficial Harry Potter Cookbook by Dinah Bucholz (Adams Media, 2010). Today, we’re going to test a couple recipes from the book. And post reaction shots. In wizard robes.

the unofficial harry potter cookbook by dinah bucholzThe cookbook contains 10 chapters and 150 recipes. While a traditional cookbook organizes its recipes under chapters like main dishes, salads, and sides, the Unofficial Potter has chapters like “Recipes from a Giant and an Elf” (Rock Cakes, Bath Buns, Treacle Fudge, Kreacher’s French Onion Soup, etc.) and “Good Food with Bad Relatives” (Lemon Pops, Knickerbocker Glory, Roast Pork Loin, Mulligatawny Soup, etc.).

The Unofficial Potter is also an interesting education in British cuisine, as recipes for crumpets, kippers, and black pudding are included, among other things. Each recipe in the cookbook is matched to a Harry Potter reference and there are also very interesting bits of culinary history. For example, did you know the first ice cream recipe came to England in the 1600s and King Charles the I swore his cook to secrecy because he wanted to keep the delicious dessert exclusive to royalty? Such a scallywag.

OK! On to the recipe tests! Katie tested 3, and I tested 1. Here we go…


ROCK CAKES, tested by Katie

The recipe for Hagrid’s infamous rock cakes was one of the first I spotted in The Unofficial Harry Potter Cookbook. I couldn’t wait to give it a go and see if they are as delicious as Hagrid claims because we all know he eats them throughout the Harry Potter series. My sous-chef son had been eager to get back into the kitchen with me after our failed attempt at making Monsieur Bon-Bon’s Top Secret “Fooj.” We’ve baked many times together, so we were confident we wouldn’t mess up this recipe!

My sous-chef carefully measured and combined all of the dry ingredients (flour, sugar, baking powder, cinnamon and salt) into a mixing bowl while I prepared the cookie sheet and turned on the oven. After we washed our hands several times, we dove into mixing the butter into the dry ingredients.

rock cakes 1It didn’t take long before the use of our fingertips turned into the use of our full fingers (and some of our hands) in order to make sure we fully incorporated the butter into the dry ingredients.

rock cakes 2After folding the egg and milk into butter mixture, we slowly mixed in the raisins. This was the only time we both grew concerned about the rock cakes. The batter seemed really thick and tough to mix. After a short while, my son didn’t have the strength to fold in the raisins so he passed the spoon over to me. Even I had a hard time making sure the raisins were fully mixed in!

Once we both determined the raisins were well combined, we dropped the dough onto the cookie sheet. We skipped using a tablespoon to measure the dough size and just eye-balled the amounts. There was a small amount of batter leftover that my son used for his own personal “teeny tiny” rock cake.

rock cakes 3We slid the cookie sheet into the oven for 25 minutes, turning the sheet once in the middle of the baking cycle. Once the rock cakes were lightly brown on the bottom, we pulled them out and set them on racks to cool. The next morning, Dr. Dana and Marissa’s office test confirmed…the recipe is a winner!

rock cake taste testRock cakes have the appearance and consistency of a scone, so they would be perfect as a morning treat with a cup of coffee or eaten in the afternoon with a spot of tea. My son and I brainstormed other filling options to use in place of raisins and we came up with dried fruits, such as cranberries, cherries or blueberries, chocolate chips, or perhaps just including a splash of vanilla extract to the dough. You could also skip adding anything and eat plain rock cakes with a pat of butter and glob of your favorite jam or jelly.

In honor of Hagrid, Dr. Dana and I set one rock cake aside and let it harden for over a week to see what would happen. It was hard, though not as hard as a rock because Ian was able to take a bite and not break a tooth. I deem the rock cakes recipe worthy of trying in your kitchen!


ACID DROPS tested by KATIE

Confident from our success with the rock cakes, my sous-chef and I moved onto another intriguing recipe: acid drops. Poor Ron Weasley had a hole burned in his tongue when his mischievous brother, Fred, gave him one to try. What would happen to us?

I had most of the necessary ingredients already, but I did have to hunt down cream of tartar, which I discovered in the spice aisle, and citric acid, which was kept with the accessories needed for home canning.

citric acid and cream of tartarAs I lined two baking sheets with parchment paper, my son measured and combined the water, sugar, and cream of tartar in a small pot. He asked for help with the corn syrup as it looked to him to be hard to measure correctly. I happily obliged to avoid a sticky syrupy mess. We followed the directions carefully, stirred the mixture constantly and used a candy thermometer once our concoction was bubbling. We watched the candy thermometer slowly rise in temperature, stirring every once in a while.

acid drops 1All was going well until the mixture reached a temperature of about 250 degrees Fahrenheit. That’s when I noticed our whitish clear blend suddenly started turning brown.

acid drops 2There was also a distinguishable burning smell being emitted from the pot. I knew this was not good, but we decided to follow through until the mixture was at 300 degrees Fahrenheit, per the recipe. Once it hit that temperature, I turned off the burner and we added the citric acid. As soon as the mixture had cooled and stopped bubbling, we took turns dropping teaspoon sized circles of the candy onto the baking sheets.

acid drops 3Total fail. Acid drops are supposed to be yellow or yellowish-white, not dark brown almost black. The smell of the candies also reaffirmed what I already knew: the sugar had scorched and the candies were a bust. On a dare, Dr. Dana tried one of the burned candies. I think this image says it all.

dr. dana taste tests burned acid dropAttempt #2. I consulted Google to find suggestions or ideas from others who have suffered similar fates with their candy. Apparently sugar is very easy to burn, so you have to be cautious when your mixture starts getting close to reaching 300 degrees Fahrenheit. Armed with this new information, I set forth to try again.

I think I may have pulled the mixture off the burner too soon because it didn’t harden into candy. It was congealed and looked like white, stringy amoebas when I dropped it onto the baking sheets.

acid drop 6Not wanting to give up, I tried the recipe for a third time. Did I finally find success? Maybe.

acid drops 5The third candy attempt definitely had a yellow appearance, smelled like lemons, and hardened into round-ish discs. The acid drops were sour to the taste, but not overly sour like I had expected. What we didn’t anticipate was once we put the acid drops into our mouths, the candy adhered itself entirely to our teeth! It was quite alarming. Here are Dr. Dana and Ian captured at the very moment the acid drops adhered to their enamel like a vise:

acid drops taste testMy takeaway from trying to make acid drops is that I’m a baker, not a candy maker. I offer a round of applause to those who can make candy because, alas, it is proven that I cannot. I’ll officially hang up my candy maker hat and leave the job to Honeydukes.


TRIPLE POWER ICY LEMON POPS tested by KATIE

My sous-chef son was thrilled when we found the lemon pops recipe in The Unofficial Harry Potter Cookbook because he has a wicked sweet tooth (like his mother) and he absolutely loves anything with lemons. He’s been known to steal lemon slices from my water glass and eat them raw without making a funny sour face.

The only ingredient that I didn’t already have in my kitchen for the lemon pops was lemon extract, which I found in the spice aisle at our local grocery store. I took care grating the zest of our lemon directly into the saucepan, making sure to not add any of the white rind because that could cause the lemon pops to have a bitter taste.

lemon pops 1My sous-chef squeezed the juice out of the zested lemon using our handy lemon/lime press, and then he added the sugar and water to the pan. After bringing the mixture to a simmer, we turned off the heat and added the lemon extract. We let the mixture cool down a bit before pouring it into our popsicle molds, then we placed the molds into the freezer.

lemon pops 2Many hours later, we gave the lemon pops a taste. Delicious! The combination of the lemon zest, juice and extract along with the added sugar gave the lemon pops a nice sweet and sour flavor that almost tasted like limoncello liquor. But trust me when I say that these popsicles were absolutely alcohol free.

Two hardy thumbs up for the Triple Power Icy Lemon Pops! We agree with Harry Potter, these popsicles are quite good!


CHOCOLATE PUDDING tested by DR. DANA

I tested something chocolate. Are you shocked? Specifically, I tested the chocolate pudding recipe in the chapter entitled “Delights Down the Alley.” We have food allergies in my house – including eggs – so pudding is usually off-limits. I was thrilled that, unlike most pudding recipes, this one was eggless! The binding agent is cornstarch.

cornstarch thumbs upI won’t send you process photos because Katie’s stove is way cleaner than mine. But I will say that this recipe is straightforward, easy, and can be made in a single pot. The ingredients are sugar, unsweetened cocoa, cornstarch, milk, cream, butter, bittersweet chocolate, vanilla, and a pinch of salt. Though simple, there is a bit of cooking magic involved in the final stove top stage – the recipe transfigures from a chocolate liquid to a thick, velvety pudding. Mmmmm.

The recipe says to strain the pudding into a bowl (I’m guessing to catch some of the inevitable lumps). But I don’t have a strainer, so I skipped that step. The pudding was a tad lumpy, but not enough to bother me or my extraordinarily picky children. Here’s a shot of the pudding before it headed into the fridge to set. Note the magic wand in front of the bowl.

pudding 1How does the Unofficial Potter pudding taste? Awesome. The milk, cream, and butter in the recipe make it rich, but not too heavy. The consistency is great too. Very smooth and creamy. Ian had a taste and found the chocolate pudding to be quite…bedazzling.

We only scratched the surface of the Unofficial Harry Potter Cookbook, but we really liked it! It’s a fantastic blend of British dishes, culinary history, and astute references to the dishes and desserts served in the Harry Potter books. It’s clear the author is either a fan of the books, a very good researcher, or both! If you are a Harry Potter fan who likes to cook, or if you are ready for some hands-on experience with meals in the wizarding world, add this book to your collection!

Magicus Extremos

wand works spell simulation game by jose m rico, background by jeremy goncalvesAre you ready to see something stunning, amazing, and totally, wickedly, cool?

Above are screen shots from the custom Harry Potter game that was featured at our library’s Wand Works event. Set in the Great Hall of Hogwarts, the Spell Simulator allows kids to test 6 spells with their wands. I’ll share the game with you first, and then introduce you to its creator, Princeton University junior José M Rico (who is, incidentally, majoring in Computer Science and co-founder of the gaming company Kapricorn Media).

For starters, we wanted the game to play on a really big screen, have good sound, and have the highest resolution possible. Instead of cobbling something together with our library’s equipment, I did one of the smartest things of my outreach career. I hired NJ Backyard Movies. They brought a huge inflatable screen, big sound speakers, and a terrific projector. Best of all, a tech guy set everything up and stayed during the event to make sure it ran smoothly.

casting a spell 1One by one, kids approached the screen, where 6 spells were displayed on a menu – Bombarda, Glacius, Incendio, Lumos Maxima, Priori Incantatem, and Protego. Once chosen, the screen would briefly display the title of the spell, its use, and its linguistic roots. Then the caster would find themselves in the Great Hall. A sparkling circle would appear. With a flick of the wand and a shout, kids would cast the spell.

Discretely to the side of the spell-casting area, and controlling the game with keystrokes, was José. He wouldn’t activate the spell unless the kids spoke the spell and flicked their wands. And he wouldn’t stop the spell until they raised or lowered their wands. This made the game appear to react to the kids’ movements.

casting a spell 2This photo also caught Téa Wimer, our Curator of Muggle Artifacts, taking a break from her exhibit to check out the game. OK. Ready to see the spells? I highly recommend dimming the lights, cranking up the sound, and viewing these full screen.

 

 

 

 

 


AMAZING, right? I must admit, I was moved to tears when José first showed me his game. The amount of time, care, and talent he put into it is truly touching. At the event, there were huge smiles, gasps of wonder, delighted laughter, and long, slow drawn out exclamations of “Whoaaaaaa….”

José has very generously modified the game so YOU can play it. Yup. Download a Windows or Mac version of the game, for free, right here.


GAME DESIGNER JOSÉ M RICO

Tell us a little about Kapricorn Media…

Kapricorn Media is a two-man game development team. It consists of Luciano Obregon, the artist and designer and my friend since childhood, and me, the programmer. It was officially named and established by us in May of 2016, though it had inadvertently started in spirit years earlier. Luciano and I have always been searching for something in this world. This has led us on a path of creation, discovery, and uncertainty that involved our early immersions into many LEGO worlds, our wooden sword fights, our hand-drawn mini games, our video game mods, and ultimately our own game development team. Kapricorn Media is our next and most mature step in this constant search.

How would you describe your relationship with the Harry Potter books?

The Harry Potter books opened up a rich universe of magic and adventure. Even though I doubt I was even capable of reading at the time the first book was published, I quickly joined the Harry Potter craze as the movies and the later books started to come out. I spent several days trying to look for the perfectly shaped stick to use as a wand, and then casting spells at my friends and imaginary enemies. I remember Luciano and I made our own Marauder’s Map at some point. I also remember having a framed photo of Luciano and me, only I had cut out a picture of Hermione Granger and pasted it on top of Luciano’s face. I had a huge crush on Hermione.

How did you decide which spells to include in the game?

I started out with a huge list of spells, and a limited amount of time to implement them. Some of them, like Wingardium Leviosa or Accio, would have required me to develop more interactive controls. Some of them weren’t as visually interesting, like Alohomora or Expelliarmus by itself. Ultimately, I chose the ones that I thought were most visually striking and made the caster feel most powerful. I also decided to add Protego and Priori Incantatem to vary the mechanics of the game by introducing an opponent.

Describe the process of building one of the spells…

Each spell had three main components: visual effects, the physical effect of the spell, and sound. I usually implemented them in that order. All visual effects involved some sort of particle system, one or more light sources to integrate the particles with the game scene, and a conduit for the spell, usually a missile or beam. The physical effect of the spell was trickiest for Bombarda, since the explosion triggers an expanding shockwave that knocks back all props in the scene. Finally, the sound design consisted of me shifting through free online sound databases. The explosion sound for Glacius, for example, contains modified audio clips of people dumping out lots of ice cubes.

How long did it take to develop the entire game?

The game probably took me a grand total of 70 to 80 hours to develop.

Which spell is your favorite?

My favorite spell is, by far, Priori Incantatem (which is not technically a spell, but more of an “event”). However, the spell with my favorite sound effects is Glacius.

What was the most creative aspect of this game for you?

The most creative aspect was choosing the appropriate way of presenting and controlling the game environment at the actual event. Even though I experimented with several options, including motion capture through webcams and Nintendo Wii remotes, I ultimately decided to do something extremely simple, yet effective. I was the one controlling the pace of the game behind the scenes. The players would point their wands and cast spells, but it would be me actually pressing the buttons and running the show. As such, the result was more of a visual effects slideshow than an actual interactive game, but I believe it was the best choice for this situation.

What was the most difficult thing to develop?

Even though I developed this game under the name of Kapricorn Media, I was mostly on my own, since Luciano was busy working on his own projects and plans at the moment. Therefore, I had to take over the visual design of the game. I had the good fortune of finding an amazing 3D rendition of the Hogwarts Great Hall by French artist Jeremy Goncalves. This scene grounded the aesthetic of the game and allowed me to take concrete decisions about the scene’s lighting and special effects.

How did event attendees react to your game?

The attendees, both children and parents, were impressed by the power of each spell cast! As the button-presser behind the scenes, I got to watch every single player flick their wand and react at the result. I saw plenty of smiles and surprised faces! There was the occasional skeptic who just shrugged and said “oh, it’s just a screen.” Most players tried one or two spells, though some of them got in line over and over again to try them all. The more attentive and talkative ones approached me and quickly realized that I was, in fact, the one controlling the flow of the game.


Many thanks to artist Jeremy Goncalves for allowing us to use his stunning 3D rendition of the Great Hall.

Wrist Owls

wrist owlsCats might make you sneeze and toads are rather old-fashioned. What you really need…is an owl! This project (which is derived from these wrist parakeets) is designed to be simple, inexpensive, and a snap to assemble at large-scale events with minimal staffing. The owls were a huge hit at a Harry Potter event we did in 2007, and again in 2017 at Wand Works.

You’ll need:

  • 1 toilet paper tube
  • Construction paper
  • A selection of small feathers
  • 1 pair of dot stickers (optional)
  • 1 small triangle of self-adhesive foam or construction paper
  • 1 pipe cleaner
  • Scissors, tape, and hole punch for construction
  • Brown or black markers

The color of your construction paper and feathers varies depending on the color of your owl. At our event, we offered both brown and white options.

Wrap a toilet paper tube with construction paper, then use tape (or glue) to attach feather wings and ear tufts. Use a marker to draw the owl’s eyes – or – use dot stickers for an extra pop of color. We added details to our sticker eyes with a Sharpie ultra fine point markers. Attach a small triangle of self-adhesive foam for the beak (or just use a snippet of orange or yellow construction paper).

The earlier incarnation of this owl project used different shades of brown construction paper for the owl’s head and its stomach:

alternative owlBut we simplified things further and just used markers to draw outlines of feathers on the owl’s chest. Finish by punching 2 holes on the bottom of the tube. Thread a pipe cleaner through the holes, then fasten the owl to your wrist. You’re ready for Hogwarts!
