I boiled the walnuts for about 15 minutes and then dried them out for a few days. I put them in the oven today for a bit. They are truly delicious, almost like eating a morel. Very rich. Maybe I should go on the black walnut diet, because they are so hard to open.
Susie gave me some chestnuts below, and showed me where to find them. Now I look for chestnut trees when I do my errands. Can't wait to roast them on the bonfire! Happy scavenging!
