“Fridges had appeared in the fifties but became widespread in the sixties. To preserve certain
foods, we sterilised them and put them in jars, in particular jams (to keep for one or two years) and fruit compotes (which would keep for up to three days). We went shopping several times a week and bought fresh produce daily. Dairy products,like butter, went rancid after 10 days, or even a week, even in the fridge, whereas now they keep for months!”
