Where do I even begin to tell this story? Another round of the Eating the Chocolate Alphabet is coming to an end, so I have mixed feelings. I’m super proud that I was able to accomplish my mission of finding a unique inclusion ingredient for each letter of the alphabet, but it’s safe to say that this “challenge” has added some grey hairs to both my head and my boyfriend’s head! ?
Remember all of his advance planning and preparation for the “X” bar?! Well, he STILL wanted to try tempering chocolate with his sous vide machine, so unbeknownst to me, he researched Z ingredients and discovered zereshk (the Persian word for barberries)! The perfect tie-in to celebrate World Chocolate Day today!
The tiny, plump, moist, jewel-like reddish-brown berries look like a cross between a dried currant and a seedless pomegranate aril.
For scale, I’ve “posed” some zereshk berries next to a U.S. penny!
These berries are a great source of vitamin C and boy are they TART! Imagine mouth-puckering tart when eaten out of hand. According to Wikipedia, Iran is the top producer of zereshk in the world. Next time I visit a Persian restaurant, you can be sure that I’ll be ordering the zereshk polo (a rice dish where the chicken has been cooked in barberry juice) to taste these berries in a different form!
Anyway, back to the story…
The step-by-step instructions and explanation of the chocolate tempering process in “layman’s terms” from this Serious Eats article by J. Kenji López-Alt, led us to believe that tempering with a sous vide circulator would be relatively easy and painless…ooh, famous last words!
A couple of weeks ago, we had some time on the weekend and tested out the process following the instructions carefully. Perhaps we (and by “we” I mean “I”) were a little over-confident. We piped the melted chocolate into the mold, placed the mold in the fridge for about 30 minutes, then unmolded it only to discover that the chocolate WAS NOT TEMPERED ?After a little research online, we discovered that the temperature ranges quoted in the article did NOT match the melting/crystallization/working information for this particular Valhrona product. WAAH! At least we didn’t waste any of the inclusion ingredients and still had plenty of chocolate for further testing. I have no photographic evidence of this chocolate failure…my ego was too “wounded”!
As “Z” week loomed, one evening during the 4th of July long weekend, we decided to employ our “lessons learned” (I have a page worth of notes and ideas of what we could do differently) from the first attempt and give tempering another shot.
So, we measured out 3 ounces of feves from the Valhrona Guanaja 70% bag that was purchased from Caputo’s in Salt Lake City, UT.
Used a vacuum sealer to remove all the air from the baggie.
Waited for the water to reach 115 degrees Fahrenheit and dropped the baggie into the pot.
The chocolate melted fairly quickly.
Then we added lots of ice to the pot to bring the temperature down to about 81-82 degrees Fahrenheit. We allowed the chocolate to enjoy its “bubble bath” at this temperature for a while and massaged the baggie at regular intervals to promote crystal formation (this is a step we neglected to perform the first time around). After about 10 minutes, we raised the temperature up to about 91 degrees Fahrenheit, still massaging the baggie at regular intervals. We thoroughly wiped down the baggie to ensure that NO water droplets were clinging to the folds. Cutting a small corner from the baggie, we piped some melted chocolate onto the back of a spoon as well as a piece of parchment paper. The spoon went into the fridge for about 3 minutes and the parchment paper remained at room temperature. When we touched the shiny chocolate with a fingertip, the chocolate ended up there, indicating that our tempering was not successful. We re-sealed the baggie and repeated the process at least 3 more times, varying the temperatures a degree or two in either direction, but still NO luck!
Have I mentioned that I have no patience, but my engineer boyfriend is tenacious and enjoys problem-solving?! So, as a last ditch effort (I was ready to quit at this point), he decided to use the “seeding method” (meaning that we took some small pieces of well-tempered chocolate and added it to the melted chocolate). Minutes’ worth of massaging and checking the temperature with an infra-red thermometer, we decided to test it one last time with the spoon and parchment paper sampling method. These were the slowest three minutes of my life…but in the end, SUCCESS!! We had tempered chocolate!
Now to pipe it into the waiting mold and add the zereshk. I have a new respect for those chocolate makers and chocolatiers who make inclusion bars look so photogenic. I tried my best, but still ended up with clumps in certain places 🙁
The mold was placed carefully onto a level shelf in the refrigerator and again we waited; this time for 10 minutes! An eternity, I tell you! TA DA…shiny chocolate with some ghosting and a few cosmetic blemishes due to imperfections in the polycarbonate mold! But no air bubbles…yippee!
The “back” on the other hand is full of lacy squiggles around the berries. I’m a chocolate blogger, not a chocolatier, remember 😉 Or maybe, that gives the bar “character”…yeah, I think I’ll stick with that theory!
We’re calling this bar Zereshk’ed Development (sorry, the “Arrested Development” play on words sounded better in my head!)
Since we had a second bag of chocolate (my BF meant to buy a different type and ended up getting the same Valhrona, though I suspect it comes from a different batch), we decided to make another bar. I’d like to say that we were vastly more successful now that we had some experience under our belts, but really the only way we were able to get tempered chocolate was by using the seeding method…AGAIN!
We are calling this bar “Zereshk Make a Deal” (since I wasn’t completely sold on the idea of adding salt as an inclusion & settled on hickory wood smoked sea salt as an acceptable option). After tasting our creation, I think the smoky flavor notes even out the harsh tartness of the berries.
For whatever reason, this one exhibited much more “ghosting” after unmolding the bar. We probably could have left it in the fridge for a little longer. Did I mention that I’m impatient?!
And though it’s hard to tell from the photo, we channeled our inner Zorro and piped the chocolate into the mold with various stylized Zs to see how it would turn out under the inclusions.
Now for the tasting notes for the “Zereshk Make a Deal” bar. There was a super sharp snap while segmenting tasting morsels. Personally, I think that the bar was a little too thick.
During the creamy, slow/even melt, there were bursts of smoky salt punctuated by chewy berries. Maybe it’s just me; but, the chocolate itself didn’t have any distinguishing flavor notes. I much preferred to “chomp” the chocolate so that the salt and berries mingled together to bring out salty, sweet, tangy and almost juicy sensations.
The “Zereshk’ed Development” bar was a bit plain in comparison. This one also had a sharp snap, but I noticed that more tiny flecks of chocolate went flying while segmenting this bar. This base chocolate had a nutty and caramel-like taste. Biting into the zereshk berries during the slow, even melt reminded me of freshly squeezed lemon juice. Of the two bars, I think I prefer the salty one.
Overall, this was an exciting way to end this round of the alphabet. From here on, I’ll leave chocolate making to the professionals! I’ll be taking a short break during the summer months (it’s HOT HOT HOT here in Southern California…predicted to be 100-101 degrees this weekend). Don’t worry, I’ll still post about chocolates here & on my Instagram feed in the meantime, but just not in alphabetical order.
Current plan for “Round 3” is ORIGINS (countries, estates, farms, etc.) Think Algeria to Zimbabwe. Please leave a comment or send me an email with any suggestions!
HAPPY WORLD CHOCOLATE DAY, hope it’s a delicious one!
