First things first, invest in some quality airtight plastic containers. Instead of leaving half open bags of pasta to go stale, or messy bags of flour in the pantry, store them in resealable containers. This will prevent weevils and other nasties, and will help keep things fresher for longer.
Next step – lock out oxygen. It's a major cause of food spoilage. By keeping it out, you're keeping nutrients and flavour in. Use plastic wrap tightly and squeeze the air out of plastic bags before you seal them.
When it comes to storing fresh fruits and vegetables in the fridge, keep them separate. Fruits tend to produce more ethylene than vegetables, a hormone that causes vegetables to spoil.
For baked goods like bread and cakes, find cool, dry places like bread bins or drawers.
Some things seem to spoil no matter what you store them in. Brown sugar for example is notorious for ruining quickly. Leave it open for just a fraction too long and you'll find it's turned from granules into a cement slab. The trick to avoiding this situation is to freeze it. Easy!
