• Safe Handling of Raw Ingredients: Always use fresh, high-quality produce. Wash all fruits and vegetables thoroughly to remove dirt and bacteria. Trim away any bruised or damaged parts.
• Using Approved Canning Methods: Only use the boiling water bath method for high-acid foods (e.g., fruits, jams, jellies, and pickles). Use a pressure canner for low-acid foods.
• Proper Cooling and Storage: After processing, let the jars cool undisturbed on a towel-lined surface. Once cooled, store the jars in a cool, dark, and dry place. Do not store canned goods in temperatures above 95°F (35°C) or below freezing.
