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!

Say it with Balloons

say it with balloonsYou love balloons. You love writing on chalkboards. Rejoice! You can finally combine your duel joys because today, we’re testing Chalkboard Balloons by NPW. Do they actually work? Well…yes. But there is one fatal flaw.

chalkboard balloons by npwThe Chalkboard Balloon kit retails for $10 and includes 1 white chalk pen, 1 small roll of white streamer (.75″ x 200″), and 20 black latex balloons, sticks, and cups. The pen is advertised as an “easy to wipe off water based chalk pen” (note the slight hint of foreshadowing here).

contents of chalkboard balloon kitDoes the kit do what it purports? Yes, definitely. After priming the pen on some paper, it wrote very smoothly on the balloon. You do have to be careful – the ink smudges when first applied. It takes about 30 seconds to dry completely.

aw yeah balloon

When it comes time to wipe the wording off your balloon, you need a damp paper towel to do so. The damp paper towel also works a treat if you accidentally get some of the ink on your skin. So the ink wipes off the balloon quickly and cleanly (yup, more foreshadowing). Question: can you erase and reuse a previously-written-on balloon?

yes balloon

Once you wipe off the ink and dry the balloon, you can definitely write something new, just like a real chalkboard. Above is the “Aw Yeah” balloon with a new message. It’s hard to see in the photo, but there is just the slightest trace of the “Aw Yeah” underneath the “Yes!”

Next question: are the black balloons in the kit special? Or will the chalkboard pen work on a plain old regular balloon? Yup. My testing revealed no difference between a black balloon from the kit and this purple one from our art supply closet.

yup balloon

At this point, I was feeling pretty good. The kit works, the balloons looks good, it’s fun to write on a balloon and then change the message. I started imagining a classroom where kids are using these balloons for a spelling bee or something. And! The kit comes with balloon cups, balloon sticks, and streamers to round out the party.

The problem, however, is what happens AFTER the party.

You see, when these balloons deflate, they follow the Law of the Conservation of Matter. Namely, nothing goes away – it just changes. Thus, the shrinking balloon sloughs off the ink as a fine white powder. Quite a lot of powder actually.

deflated mess

It gets worse. While the powdered ink does vacuum up tidily, if you dab the powder with water or baby wipes, it leaves a stain that sets into your carpet with a vengeance. IT ALSO DOES THIS TO YOUR CLOTHES. I pressed a little too hard with the pen while writing on a balloon and it popped. The powder hit my pants and sunk in. I didn’t even have time to brush it off or attempt a rescue mission with a damp cloth (which wouldn’t have done anything anyway). I treated my pants with stain remover. I laundered them. Nope. That stain is here to stay.

stain on pants

NO WHERE on the packaging or pen does it say that the ink could stain your carpets and clothes. The packing does warns you (in 4 different languages) that balloons are choking hazards for kids under 8. But nothing about the ink permanently STAINING YOUR PROPERTY! Perhaps this is a bit naive, but if the packaging says “easy to wipe off water based chalk pen” and doesn’t provide a warning, you just assume that this won’t seize your carpets and clothes and never let go. YOU OWE ME A PAIR OF CARGO PANTS CHALKBOARD BALLOONS BY NPW!

So I’m afraid I can’t recommend this kit. Yes, the white ink on the black balloons looks cool, but you can achieve the same effect using a silver metallic Sharpie marker. See?

it works balloon

If, however, you want to flirt with disaster and use this kit at your next shindig, make sure to do 3 things: 1) Wear grubby sweatpants while writing messages on the balloons; 2) Deflate the balloons over a garbage can to avoid marring your carpets; 3) Tell all your party goers to keep 6 feet from the balloons at all times. Because if they pop? There will be stains.

Don’t Try This At Home Kids

don't try this at homeA monkey on a unicycle rolls down a ramp towards a snake. The bar holding the snake drops, which causes a bag of peanuts to fall into a container that sends a cart down a ramp into a tennis racket rigged to a mechanism that touches a match to a cannon fuse and fires an acrobat through a ring of fire!

Rube Goldberg’s inventive cartoons have fascinated me since I was a kid. A few years ago, our library even hosted a Rube Goldberg program, complete with a behemoth of a page turner and other activities. So imagine my delight when I spotted Wonderology’s Rube Goldberg kits on the shelves at Target.

wonderology rube goldberg kitsIntended for ages 8 and up, Wonderology offers 6 different kits that cost between $10 – $20. Each kit contains a plethora of parts and a fully illustrated set of instructions. I purchased the Acrobat Challenge, the Garden Challenge, and the Speeding Car Challenge, then invited 3 kid testers (ages 6, 8, and 10) to try them out.

kid testers at workThe kids were very excited as they unpacked the kits. The parts are fun, bright, and nice quality plastic. Here, for example, are the various pieces of the Acrobat Challenge:

acrobat challenge kit partsHere are the kit’s illustrated instructions. They’re presented in classic Rube Goldberg format (they even use his special font!):

acrobat challenge instructionsBut as soon as construction started on the kits, well…that’s when things started to go wrong. Take the Acrobat Challenge, for example. In one part of the instructions, it clearly shows the yellow “monkey release” flag facing right. In two other sections of the instructions, it’s facing to the left! Also, either way I turned the flag, I never could get the monkey to work quite right.

problem with instructionsThere was a lot more of this I’m afraid – mechanisms not working like the instructions suggested, confusion with where to place the various pieces, the whole schbang toppling over when you tried to adjust it. Soon, there were shouts of frustration, explosive sounds of exasperation, creative G-rated cursing, and a box kicked across the floor (and it wasn’t just the kids doing all that).

Between me and the 6 year-old, we never did get the Acrobat Challenge to work. So our kid tester used it like a play set instead, creating and narrating an involved story about a monkey snake circus. Cool.

Meanwhile, things were looking a bit more promising at the Speeding Car Challenge. It was, against all odds, assembled with somewhat minimal adult assistance.

speeding car challengeBut…see that chicken? It’s supposed to get a feather “plucked” from its tail, which causes it to lay an egg, which triggers the tennis racket, etc. But the egg just wouldn’t stay under the chicken. It just kept dropping and triggering the rest of the mechanism. So you had to skip the chicken all together, which is rather disappointing.

Also, the 8 year-old kid tester wants you to know that the balloon on the car is a little tricky. Once you blow it up, you have to: 1) Block the tailpipe with your finger; 2) Rapidly remove your finger; then 3) Plug in a plastic cork in juuuuuust right. The seal on the balloon starts to leak pretty quickly too. But it was, he admits, a cool-looking car.

balloon car testSo that just leaves the Garden Challenge. This kit was particularly intriguing to me because it involves real water! Our 10 year-old tester managed to assemble it just fine.

the garden challengeBut we soon discovered a fatal manufacturing flaw. See the orange gutter at the top of the mechanism? It’s supposed to tilt downward and let the 8 ball roll down and hit the watering can. But there was a little plastic piece that wouldn’t allow the gutter to tip down far enough! Katie had to saw the piece off with a box cutter in order to get it to finally work.

bad partThen it was test, adjust, retest, adjust, curse quietly under one’s breath, test, adjust, and retest. It took dozens and dozens of attempts, close to an hour of concentration, and Katie’s sheer determination to get it to work. And yes, I did say work. Katie and the kid tester got it to work! Drumroll please…


OK. So maybe the ball bounced off that final ramp, but I’ll take it and call it DONE.

I really admire Wonderology’s concept. The kits are a clever idea, they look fantastic, and the quality of the plastic is good. However, they’re simply not for kids. Especially 8 – 10 year-olds (unless said 8 – 10 year-olds have the patience of saints and the hands of neurosurgeons). Heck, some of us adults had trouble getting them to work! Our testing group found them difficult and rather vexing. While we ultimately had success with one kit, we encountered enough flaws along the way that the ultimate take-away was more exhaustion than exhilaration. Alas, not recommended.
