With food, we not only waste valuable food, but also a lot of money without realising it. Avoid waste in the kitchen and save a lot of money with these tips:

1. some recipes only use the egg white. It is not necessary to throw away the yolk, because both egg whites and yolks can be frozen and used later. To freeze egg whites, pour them into a plastic ice cube tray. Use one egg white per compartment. You can remove the hard frozen egg white cubes and store them in a plastic bag in the freezer.
You can freeze egg yolks by adding a little salt or sugar. This prevents curdling. Then freeze the yolks in the same way as the egg whites.

2. bananas with brown spots are only very ripe, but not yet rotten. If you don't want to eat them like that, use them in recipes like banana bread or cakes. You can also mash the banana and freeze it for later use in milkshakes.

3. cottage cheese stays fresh longer if it is upside down in the fridge. You can also freeze cottage cheese, but then you have to add some cream when defrosting it so that it becomes creamy again.

If you only need a few drops of lemon juice, you don't have to cut open the whole fruit. Poke a hole with a toothpick and squeeze out the drops. The rest of the fruit will keep for a few days.

Don't throw away the stalks of asparagus, broccoli, cauliflower and other vegetables. Steam them until they are soft and process them into a puree. You can use the puree for soups and sauces. The puree made from vegetable stalks makes soups and sauces creamier, but has fewer calories than cream. You can also puree leftover vegetables and use them in this way.

For a richer flavour in sauces or soups, add a tablespoon of dry milk. Powdered milk is usually cheaper than cream and lasts longer.

7. for the best nutritional value and the same money, choose fruits and vegetables with bright and bold colours. For leafy vegetables, the darker the green, the more nutritious.

If a food item is on sale and you have space in the freezer, buy extra.

When buying meat, you can save money by buying lean meat. To make the lean meat taste just as good, you can marinate it before cooking and cook it slowly.
