When Julie and I went to Maker Faire a few months ago, we were drawn to 2 demonstrations of molecular gastronomy, a new technique for cooking and looking at food that explores the science behind it. For example, one demonstration was of carrot juice caviar, made by mixing the carrot juice with calcium lactate and using a eyedropper to drip it into a bath of sodium alginate, where it solidifies. Neat stuff.
For graduation, Julie and her family got me a nice molecular gastronomy kit to try some of these things on our own. It came along with a DVD with demonstrations of various ways to use the tools and substances, which mostly involve changing the form of foods: turn ketchup and mustard into little balls, make foam out of garlic, etc. The footage is very chic as well, with no voiceover, an upbeat, jazzy soundtrack, and perfectly clean and careful execution.
Since I happen to have a large slab of dark chocolate lying around, we decided to try one recipe to make dark chocolate spaghetti. It's exactly what it sounds like: dark chocolate in the shape of spaghetti.
The first step in making it is to melt the dark chocolate and combine it with agar, a substance similar to gelatin (or jello). Once it's boiling and mixed, it gets poured out into another container where it begins to take shape.
Using a syringe, we forced the dark chocolate mixture into tubing, which was then suspended in an ice bath to cool it down. This step ended up being particularly fun and not too difficult.


The real trick came with getting it out. After it cools for a bit, you use the syringe again to force air through the tubing, which pushes the dark chocolate out the other end. Or so the video led us to believe.
There were some issues. First, the dark chocolate didn't form a perfect vacuum or wasn't completely solid, so when the air was forced in (with great effort), it would create a bubble alongside the chocolate instead. When it did come out, it did so very suddenly in one big push, though that would often cause the dark chocolate to fracture as well.
And it was accompanied by the squeezing sound as all the air got through, so I understand why the video had music playing over instead. To summarize, brown semi-solid coming out, accompanied with sound. It was very appetizing.
Even so, we managed to get a couple good, long strands out before the bulk of the chocolate in our container began to solidify. We tried to microwave it and give it a second chance, but there was no luck there, either. In the end, there was much wreckage.
But enough successes. We took the best strands, draped them over some strawberries and graham crackers, then put some whipped cream on top. It was yummy.
