Several years ago I picked up a lot of acorns and was going to cook with them, and the bugs ate them first. My live oak trees have an abundance of acorns this year, and I gathered a five gallon bucket full. Found a recipe for pancakes and had them this morning. Making flour seemed like a lot of work so I used them as chopped nuts. I did chew and taste one to see how much tannin they had. They tasted bland. Chopped a half cup and put them in a coffee filter them put in four cups of water to leach out the tannin. The water came out with not much tannin in the pot. I have also read that putting them in a gas oven with pilot light to dry and, kill insects. Think I will try them in banana nut bread next.
