A friend fixed a treat in camp once, long ago, which I had never seen. It was a huge puffball mushroom. It was at least 12" in diameter, and he got it at the perfect time, while it was still absolutely white, firm and sort of brittle. Not long after that stage they quickly go yellow-tan-brown-blackish, get leathery and then change mostly into black, smoky spores. He cut thick slices, dipped them in batter and deep fried them golden brown. It doesn't get any better.
I've been trying to remember where I once stumbled on a patch of wild hazelnuts, can't dredge it up. They were dead ripe and I ate them straight off the bush, excellent.
