For most of us, buying powdered eggs isn't a good option for food storage because of how expensive powdered eggs can be. Well, there is a cheaper alternative. Vegans use flax seed as an egg substitute. Flax seed is a healthy alternative, high in fiber, in addition to being less expensive: a 16oz box costs between $3-4. (source and here)
Because of the nutty flavor, flax seed substitution is generally only used in baking: breads, pancakes, waffles, cookies, etc.
Take one tablespoon of milled flax seed. You can either buy it milled, or grind up the kernels in your grinder.
Add 3 tablespoons of water (amount of water may vary per recipe, but this is a pretty basic measurement).
Flax seed is like wheat flour in that after it is milled (ground) it needs to be stored in the fridge. So after you open a box of milled flax seed, stick it in your fridge. Actually seeds can be stored in the pantry until ground.
Flax seed can be found in health stores or in your local grocery store by the oat bran and other "hot" cereals.
Have any of you used flax seed before? Maybe in a different use than egg substitution?
