I don't batch cook. I sometimes cook slightly bigger amounts with the intention of putting portions in the freezer for another day. It doesn't happen often as someone in the house will fancy a light supper and stuff their face with one of the portions and then someone else will eat the other for their lunch. If there's more spare portions then they get put into the freezer.
Do you batch cook? If so what's the purpose? Is it just to have a "home made ready meal" in the freezer? Time saving, money saving, energy saving?
If you batch cook, how many portions do you cook at a time?
