Soy lecithin powder is an emulsifier used to produce liquid emulsions and very light foams called airs. The light foams produced with soy lecithin can also be frozen to create a solid airy foam.
These light foams or airs are quite simple to make. Just mix your liquid with soy lecithin powder using an immersion blender and then introduce air into the emulsion by lifting the immersion blender up to the surface of the liquid.
