Begin with whole, raw flax seeds. Buying pre-ground flax is a dangerous game, as the oil is very unstable, and once released (via grinding) it will turn rancid pretty quickly. So buy your flax seeds whole and grind them yourself, to spec. It’s easy enough; you can use a coffee grinder, a hand-crank spice grinder, a mortar and pestle, or a high-speed blender. Process into a very fine powder.
Store whole flax seeds in the refrigerator or freezer.
Make egg/s. One egg equals [1 tablespoon flax meal plus 3 tablespoons water], and you do not need to make each one individually. In a small bowl, add flax meal followed by water (not water followed by flax), stirring as you go. I use a miniature whisk because it’s adorable, but a fork works just as well.
Refrigerate. This is key! Place the bowl of eggs in the refrigerator for a minimum of 15 minutes, but up to an hour is best. This will allow your egg to “set up”. Don’t skip this important step!
I always make my eggs at the start of a recipe. That way, I can get them in the fridge, and then work through the other steps while the eggs set.
When the eggs come out of the fridge they’ll have formed a thick sticky goo, just the consistency of egg whites. There’s your binder! Add it to the recipe and proceed as instructed.
