I love Bob’s Red Mill products. I use their egg replacer (https://myegglessworld.wordpress.com/2013/04/11/14/) and their flax seed products as well as their steel cut oats. Flax seed can also be used as an egg replacer. You can buy the seeds whole and grind them yourself or you can buy them already ground. Flax seeds that are already ground do not last very long so you can keep them in your freezer to extend the shelf life. I buy the pre-ground Flax seed meal and add it to a lot of breads, pizza dough and anything that has whole wheat flour in it as well. It bumps up the nutrition and adds a nutty flavor.
If you want to use it as an egg replacer you can mix 1 tbsp ground flax seed with 3 tbsp of water. I often just add it in to the dry ingredients, sometimes in addition to the Bob’s Red Mill Egg Replacer.
