For Design Frontiers class, I tried sperification of foods.  I used Sodium Alginate, Calcium Chloride and  Calcium Lactate Gluconate, and tried both sperification and reverse-sperification, with Root, a liquour, water, tomato juice, milk, and olive oil. I was really only successfull with the water and tomato juice, probably because I failed to use purified water for my water-bath.  I'd like to try this again in a more controlled environment. More photos after the jump.
