We had in the freezer some forgotten potato soup. artan_eter came to the conclusion that it wasn't going to be eaten unless Something Got Done To It, due to the fact that we'd forgotten it, and thus hauled it out to Do Something.

His first attempt was 'let's thicken thus up and try to make potato pancakes out of it'.

This ... produced a pan coated in burnt potato bits.

He made a casserole out of it instead.
