Exploring preservation methods for excess harvest

  1. Freezing: Blanch vegetables like beans, peas, or corn in boiling water for a few minutes, then quickly cool them in ice water. Pack them into freezer-safe bags or containers for long-term storage.
  2. Canning: Preserve excess tomatoes by making homemade tomato sauce or salsa. Follow proper canning techniques to ensure safety and store the jars in a cool, dark place.
  3. Pickling: Create flavorful pickles by brining cucumbers, peppers, or other vegetables in vinegar, water, and spices. Store the pickles in sterilized jars in the refrigerator for a tangy and crisp snack.
  4. Drying: Dry herbs by hanging them upside down in a cool, well-ventilated area until they are completely dry. Store the dried herbs in airtight containers for later use.
  5. Herb-infused oils: Infuse oils with fresh herbs like basil, rosemary, or thyme. Place the herbs in a bottle, cover with oil, and let it sit for a few weeks to infuse the flavors. Strain the oil and store it in a cool, dark place for use in dressings, marinades, or cooking.
