Knowing what should and shouldn’t be stored in the fridge is a nightmare, says Sarah Rainey in the Daily Mail. So here are some rough rules. Keep soft veg – tomatoes, cucumbers, peppers and aubergines – out, but stick root vegetables such as carrots and parsnips inside, preferably “in a container filled with cold water”. Opened tomato ketchup is fine in the cupboard. Nuts and flour last longer if they’re kept chilled. Final tip: if your fridge starts to pong, just stick a peeled potato on the middle shelf. “The starchy flesh sucks bad odours out of the air.”
