In this video watch Michael Zbyszynksi, explain how to make carrot caviar in this video. He starts with a beaker of ordinary carrot juice mixed with sodium alginate -- a derivative of seaweed -- at a ratio of 2 grams of sodium alginate to 250 grams of carrot juice (a 0.8 percent solution). He then uses a syringe to drop small beads of the solution into a bath of water with a couple grams of calcium chloride dissolved in it. The calcium chloride hardens the sodium alginate from the outside in, giving it a "skin" that holds the carrot juice inside. After rinsing in plain water, the caviar-like beads are ready to be used as a surprising garnish. Nifty!
