I've read every post and haven't found one which I don't do !!! Mrs Thrifty, moi…
Re the chicken carcass, roast it until it's brown to get a better flavoured stock.
I cook on an electric Aga and after switching off the hotplate, put a kettle of water on it to absorb the remaining heat and use it for the washing up---( no dishwasher in the chicken run!).
I bake my own bread ( buy bread flour by the sack from a mill) and cut the loaves into portions for just one day and freeze them (recycled plastic bags) but even then sometimes have a stale bit, so keep a bag in the freezer and add any stale bits to it until there's enough to make a delicious bread pudding.
Any lettuces in the garden that are beginning to bolt are dropped into boiling water, drained, liquidised and frozen in recycled butter spread tubs for winter when they make a lovely soup with a tin of peas and some mint.
Before eating an orange, I grate the rind onto a little bit of clingfilm and freeze the little parcel to flavour cakes.
I freeze herbs in ice cubes during the summer to use in winter.
As you can guess, I'm a wartime child and nothing was ever wasted in our house.
