When I'm looking up egg substitutes, one of the easiest (for me) is making a slurry of flax seeds and water. However, I noticed there is a difference between using the flax seeds whole and breaking them up. The slurry is thicker if the seeds aren't whole. Or at least, that's what I think I observe.
So, should you only used broken or whole flax seeds, when using them as an egg substitute? Are there (dis)advantages of using flax seeds whole vs. broken up?
I've seen this question, that mentions to break them up, but it isn't specifically about substituting eggs.
Note: I can imagine it also depends if I mind pieces in whatever I'm making, and I don't mind about those.
