We used corn flakes, 3 eggs (had chickens, have them now too), Worcestershire, onions, and maybe celery, mixing it by hand was good fun to me for some reason. As an adult when I started growing mushrooms, I added a bunch from a flush that produced way too many to use and was starting to go bad, and omg I love it that way now! (Not necessarily mushrooms on the edge of going bad, but is a good way to use a lot up and freeze for later meals!)
