Well, no more. This year we are planning on doing a big shop hopefully just once a month, and we won't be going food shopping at all in between, if we can help it. Let's face it, even things like milk, cheese, butter and veggies can be frozen, so if we buy a month's worth then we shouldn't, in theory, run out of anything. Well, except possibly for salad stuff, until home grown things are ready.
I'm going to keep all my shopping receipts in an accounts book and total them up every 3 months. That way I should be able to get a realistic idea of how much we actually need to allocate for shopping.
I'm also going to try to avoid having any food waste at all - we are usually pretty good at this anyway, but will endeavour to keep on top of using up fresh food before it goes off, and freezing even small leftover amounts of cooked food and using it up in another meal at a later date. I'm also going to make more of an effort to use up everything we have in the cupboards and freezer....we do seem to have a habit of keeping especially tinned and packet food for months and months, and frozen stuff that finds its way to the back of the freezer and gets forgotten about.
