How to store onions
You will need:
- A ventilated box for storage
- A dark cupboard
1. Remove you onions from their current packaging – particularly if it's plastic.
2. Take a look through your onions. If you spot any growing mould, we'd recommend storing them separately to reduce the spread of mould to otherwise healthy onions. They don't have to be thrown away, we'd just recommend that you use them as soon as possible.
3. Place your onions in a container with plenty of ventilation. This is to prevent them getting too damp and to prolong their life.
4. Place your onions in a cool, dark cupboard. Somewhere between four and 10ºC is widely considered optimal.
Top tip: Peeled onions are best kept in a sealed container, in the fridge. They should last up to 14 days.
