Aug 10, 2015 - Spherification is kitchen alchemy; a technique that enables you to imbue a flavorful liquid with the appearance of being solid, an illusion that's broken when the spheres burst with flavor as they're eaten. After several unsuccessful attempts to improve the spherification technique, el Bulli team realized that they could just try a reverse spherification by reversing the components. This phase was thus defined as Technology and Efficiency. I used 2 different kinds to add some color variety in our experiment. I then added xantham gum and got something closer to globules but they were very irregular. Instead of struggling to tell which chromosome is which from... Overview Instead of adding alginate to the liquid to be spherified, we add the calcium ions to the liquid, and then put this into an alginate bath. There are some excellent videos on Modernist Pantry’s ChefSteps partner site that make it look easier than it is. STEM Library Lab is temporarily closed for Summer Break!
