Each kind of fruit or vegetable has its season, when it is plentiful. What you don’t use now can be useful later. How do you preserve them?
The best time to eat fruit and vegetables is when they are harvested naturally. This is when they are healthiest and most plentiful. However, this is not the only time you can eat them. Tomatoes arrive in summer and autumn but are still used to prepare meals in winter.
In shops you can find out-of-season food products which come from glasshouses and cold stores or are imported from abroad. But the fruit and vegetables that are available in the largest quantities are the season’s produce, whose quality (and price) will be the best.
