Chillies are kept in the refrigerator in a paper bag for a week. They can be dried in the sun to make them last for months or blanched and frozen. You can also preserve them whole or chopped in oil for three months. You can wash and blend them to prepare sauces or chop them well to add them to mousses or hot chocolate. In order to prepare a jam, you can also cook them with sugar and wine for an hour, filter them and cook them for another 30 minutes.
