This egg substitute really works! I’ve used it for baking very successfully, although note that it doesn’t leaven like eggs for soufflés or sponge cakes. I’ve adapted this recipe from a great book called The Allergy Self-Help Cookbook by Marjorie Hurt Jones, R.N.
Here is the recipe for substituting 1 egg:
1/3 cup water
1 tablespoon whole flaxseed (available in most health food stores)
Place the water and flaxseed in a pan, and bring to a boil. Lower the heat and simmer, watching closely as the mixture thickens to a gel (about 5 minutes). Remove the pan from the heat before the mixture gets too thick and gummy. The flaxseeds don’t need to be removed from the gel.
