Steps to effectively preserve pickles:

Choose Fresh Ingredients: Ensure the vegetables or fruits you're pickling are fresh and free from any signs of spoilage.

Clean and Sterilize: Wash the vegetables thoroughly and sterilize the jars or containers you will use for pickling.

Dry Thoroughly: Make sure both the vegetables and the containers are completely dry before starting the pickling process.

Use Quality Vinegar: Vinegar acts as a preservative and should have a minimum acidity level of 5%.

Add Salt and Spices: Non-iodized Salt not only enhances flavor but also helps in preserving the pickles. Add spices like mustard seeds, peppercorns, or cloves for flavor.

Seal Jars Properly: Ensure that the pickles are fully submerged in vinegar and that there are no air bubbles trapped in the jars. Seal the jars tightly with sterilized lids.

Store in a Cool, Dry Place: Place the sealed jars in a cool, dark place away from direct sunlight.
