*nods* re dribbling in extra liquid to get it to the right consistency.

You think a porridge jug is bad? Try a billy can - about 25cm radius, full of enough porridge to feed 25 people ish, that's been on a wood fire. Cleaning that pot is a horrible job - the outside's far easier to clean than the inside (washing up liquid painted on the outside makes it a lot easier to clean), and the job either goes to the girls who've been noisy at night or gets left for the adult cooks to do.
