one-half of a banana, mashed;
two ounces of mashed potatoes;
two ounces of nut butters;
two ounces of mashed beans;
one-fourth cup of applesauce;
one-fourth cup of pureed fruit;
two ounces of soft tofu blended with some water;
one teaspoon of soy flour mixed with one tablespoon of water;
one tablespoon of flax seeds blended well with three tablespoons of water. (This mixture can also be boiled until it develops the desired consistency). Flax seeds should be stored in the freezer, as they can become rancid at room temperature or in the refrigerator.
Another egg substitute is Ener-G Egg Replacer, a commercial egg replacer made of potato starch, tapioca flour, leavening agents (calcium lactate [vegan], calcium carbonate, and citric acid) and a gum derived from cottonseed.
