you have to be ruthless about The List
itemise everything, and also try and tie it in with a menu plan, I try to go for a week to ten days, nobble everyone in the house as to when they are in or out for meals and plan.
I have a American Style FF in the kitchen and a mahoosive seven foot chest freezer in the shed
I have two lists, Inside freezer and Outside freezer... they are a thing of beauty and I re-write them when there are too many crossings out :D
Dh is on his FINAL warning sort of a joke, but not really for taking stuff out and not crossing it off....somehow that seems to be where the system falls down. Everyone wants to write stuff on the list, they are less keen to cross it off.
Also, label everything, chilli/bolognese/cottage pie all look very similar as does gravy and soup as dh found to his cost....expecting a nice bowl of soup for his lunch at work turned out to be onion gravy. LOL!
