So, for those of you who don't like eating too many eggs, or if you've run out and it's baking time....just use flax seeds. IF you don't have flax seeds in your house, then now's the time to get some. They're loaded with omega 3's, like fish and such. Good source of soluble fiber and especially good for those with high cholesterol. Eating 1 T a day is a recommendation from the mayo-clinic.
Use 1 T ground flax seed with 3 T water as an egg substitute for baking. Just mix that in with the liquid ingredients and it starts to form a type of gel (I've heard you can use this gel for hair gel, but haven't tried it). I've had success with cookies and muffins so far.
When you don't need it for a substitute, get your extra omega-3's by sprinkling flax on your hot morning cereals or your cottage cheese, or on your sandwich, etc. Or even add it to your homemade granola.
Tip: store flax seeds in your fridge or freezer. And it's best to grind them when you use them, so as to maximize the nutrients (which diminish more quickly if stored ground). You can use a coffee grinder to grind them, but they are hard on pepper mills and too oily for many wheat grinders, so be careful. (If you don't have any of these, you can just buy the pre-ground...but remember to store in your fridge.)
