Freezing, boiling down or even vacuuming are common methods of making some foods last longer. But how can fresh foods such as avocados, onions or carrots be kept fresh for longer? There are actually a few very simple tricks.

Drizzle avocados with lemon juice
Once cut open, avocados will turn brown quickly. If you only use half of the fruit for the time being, you should definitely leave the pit in the other half. This protects the part underneath the core from turning brown and soft. And there is also a trick for the exposed areas: Simply drizzle with a little lemon juice or olive oil - both slow down the oxidation process of the avocado.
Wrap bread in kitchen towel
Bread often becomes dry and hard after just one day. The best way to keep it fresh for as long as possible is to wrap it in a kitchen towel and then put it in a paper bag. This allows the bread to breathe without drying out and stays fresh for longer.
Knot onions in nylon stockings
Onions can be kept for a relatively long time without our intervention, but even here there is a trick that can be used to help. What it takes are long nylon stockings. Simply place one onion at a time in a discarded stocking and tie a knot after each one so that the onions are separated from each other. This keeps them airy and dry and they stay fresh for longer. Depending on your needs, simply separate the stocking over the knot.
Cut the spring onions into rings
Spring onions add the right flavor to almost every dish, but they don't keep very well. There is a simple solution to this: cut open the spring onions as if they are about to be processed. Then pat the rings dry and place in an empty, dry plastic bottle. Then store them in the fridge.
Store carrots in newspaper
Carrots taste best when they are crisp. Unfortunately, the vegetables quickly lose moisture and thus their consistency, which is why they should always be kept in the refrigerator. Wrapped in newspaper or in a cling bag with some air holes to prevent mold growth, carrots will stay fresh and crisp for longer.
Store potatoes and apples together
Two that keep longer together are apples and potatoes. The latter will sooner or later begin to drift. However, if you keep apples close to the tubers, this process is significantly slowed down and the potatoes stay edible longer.
Soak strawberries in vinegar
Strawberry season has begun, just a pity that the red berries spoil so easily. A trick: Simply dip fresh strawberries in a vinegar-water bath (1 part vinegar, 10 parts water) and then dry well. This kills bacteria on the surface and makes the strawberries last longer.
