Cherry tomatoes can be preserved in several ways, including: Freezing: Wash and dry the cherry tomatoes, then freeze them in a single layer on a baking sheet. Once frozen, transfer them to a freezer bag or container. Canning: Blanch the cherry tomatoes in boiling water for 1-2 minutes, then peel them and pack them in sterilized jars with a bit of salt and lemon juice. Process the jars in a water bath for 15-20 minutes. Drying: Cut the cherry tomatoes in half and arrange them in a single layer on a baking sheet. Sprinkle them with salt and any desired herbs, then dry them in a low-temperature oven (around 200°F) for 6-8 hours, until they're completely dry. Store them in an airtight container with some olive oil.
