How to preserve fruits and vegetables without electricity.
Fruits and vegetables are all differents. That's why they need different environments, mainly based on ambient temperature, light and relative humidity.
ADVICE There are sometimes several ways to preserve fruits and vegetables. The best way to choose is to try !
An aerated shelter where insects do not have access. You can keep an eye on fragile food, mainly small fruits as bananas, berries, cherries, avocados. To avoid fruits and vegetables as tomatos and peppers wilting, place them next to some water to hydrate them.
Here, fruits mature. For faster maturation, place them next to an apple or a banana as they produce ethylene.
Evaporation creates fresh air. With a permeable material which lets water steam go, evaporation refreshes food. Faience is a kind or ceramics, permeable when it's not glazed. Among other things, it's used to do pots. This technique is called Zeer Pot and is composed of two ceramics pots, separated with humid sand.
Garden pots are deep. We use baskets to avoid crushed fruits. The temperature, between 10°C and 15°C (50°F and 59°F), can also preserve butter, milk and cheese a few days.
Some vegetables can stay buried in the garden after their growth, to be protected from outside environment. Root type of vegetables are placed in the sand, dry or humid.
If you have a cat at home, it is highly recommended for your carrots that he does not have access to the sand.
