Haslet is still made and sold by pork butchers in Lincolnshire and Nottinghamshire (probably elsewhere but I know about those). Much nicer than the stuff sold in supermarkets on the cold meats counter, full of onion and fat, which is the only sort I can find further south. Lincolnshire ones are lovely, particularly the brown bits on the outside.
I used to love pork dripping on bread as a child, especially the dark brown jelly. We had it after we had had roast pork, or you could buy the dripping from the butcher too.
Tinned peaches and evaporated milk! Bottles of orange drink, about a third of a pint, bought from the milkman.
