Look twice at rice
Think before pitching rice if it’s been sitting in your cupboard for a few months. It can be used to dry electronics if you get them wet – just put the device in a bowl of the dry grains for 24 hours.
Banish sponge bacteria
Your old sponge might look like it belongs in the bin, but two minutes in the microwave will kill as much as 99.9 per cent of the bacteria on it, making it good as new. Be sure to get it wet first.
Celery care 101
Celery is all about crispness, so when it starts to go soft, you may as well throw it out. Right? Not necessarily. Try this first: put limp stalks in a bowl of cold water with a few slices of raw potato. After an hour or so in this starchy bath, the stalks may deliver the crunch you expect.
And while even crisp celery may turn brown, you can stop browning before it starts. Before storing the stalks in the fridge, soak them for 30 minutes in 1 litre cold water mixed with 1 teaspoon lemon juice – a trick that will also crisp celery just before it’s served.
