This is probably common knowledge, but I just recently discovered it. As a replacement for eggwhites in sours, I was purchasing aquafaba which, works great but, is quite expensive. I found out it's much less expensive to by a can of Chick Peas (Garbanzo Beans) for 99 cents and it gives about 5-6 oz of aquafaba. For me, that works for about 10-12 cocktails, so replaces a dozen eggs for a fraction of the cost. Then I take the left over chick peas and dry/season/roast in the oven or air fryer and it makes a great healthy bar snack. The water will last about 4-5 days once opened/strained.
