One time I decided I was going to try this recipe for hazelnut soup. It was from an American Indian cookbook. But it apparently was meant to feed the entire tribe - it made 24 servings, and was supposed to simmer for like 4 hours!! So I divided everything by 4 and made it for 6.
That was fine, except I didn't think to reduce the cooking time. About an hour into the simmering, my roommate chanced to walk by the pot... and notice that almost all the liquid had boiled away.
We ate it anyway. It actually didn't taste too bad!
