Sorbet 101 – a trick to getting a smooth sorbet from any juice!

One of the reasons I went to culinary school, after working in professional kitchens for a few years, was to have an understanding of why my recipes didn’t always work. Things would succeed if I followed the recipe to the letter, but if I played or strayed at all they would have as much chance of being a disaster as they did a winner. In culinary school I learned enough about food science to be able to play with recipes or create my own from scratch. I learned why eggs should be warm when you whip them and why you should use low protein flours for cakes and higher ones for breads. They taught me about Brix, Baume and other technical ways to measure sugar in sorbet solutions so they will freeze, but not become a solid brick of ice. After school, once I could afford it, I bought a Refractometer, which shows you the sugar content in a solution. This way I can mix up a batch of any kind of fruit sorbet, add some simple syrup and the sorbet will be a success. But, what if you are just making sorbet a couple times a year, do you really need such a geeky, expensive gadget? Not unless you are a kitchen equipment hoarder, like me.

So, then what? There is another way to have a greater chance at success than just praying for the best. You can use a method that involves floating an egg in your sorbet. Yep, I said FLOATING AN EGG, the whole thing, in the shell. It is also a very cool experiment to do with your kids. As the solution gets more saturated with sugar, the egg is buoyed to the surface. Once the egg is actually floating partially above the surface, the solution has enough sugar to prevent the sorbet from being too icy. Perhaps not as impressive as whipping out your refractometer, but pretty amazing in a Beakman’s World kind of way and it allows you to make sorbet from just about any juice. Obviously, this will not work with all fruits, banana puree tends to be too thick and the egg, no matter how sweet the solution, will float on the surface. But, for citrus and other thin juices, it is wonderful. (more…)
