As a family we try to limit our consumption of animal products. This is not only for health reasons, but it is also a money saver. We do eat eggs from time to time but when we do we usually spend a little more for higher quality organic eggs from Costco for about $0.28 an egg. Most people pay closer to $2.00 a dozen or $0.166 an egg.
Anyway, here's how you do it for one egg!
In a small bowl mix a tablespoon of flax meal with three tablespoons of warm water.
Let it sit for about 3 minutes.
Stick a fork in it because it's done! (don't actually stick a fork in it).
It will look like this.
We use this as a substitute in all kinds of recipes that include baking, cooking etc.
We have also used a hybrid for some things that need that super strong binding ability of eggs in which we will use one flax meal substitute egg and an actual egg. However, we find that this quick trick works really well for daily uses and it saves us money while givings us a wider range on nutrients.
The health benefits of flax meal are wonderful as it is very high in fiber and in essential fatty acids.
