How to store homemade tomato paste without refrigeration?

Question

Learn storage methods to keep tomato paste fresh without using a fridge.

Answer 1

To store homemade tomato paste without refrigeration, you can preserve it by canning using a boiling water bath method or by drying it into tomato leather. These methods create an environment unsuitable for microbial growth, ensuring its preservation.

Detailed Explanation:

Storing homemade tomato paste without refrigeration requires creating conditions that prevent spoilage. Here are two effective methods:

1. Canning (Boiling Water Bath):

1. Prepare Jars and Lids: Sterilize canning jars and lids by boiling them in water for 10 minutes.
2. Fill Jars: Fill the sterilized jars with hot tomato paste, leaving 1/2 inch of headspace.
3. Remove Air Bubbles: Gently tap the jars or use a non-metallic utensil to release any trapped air bubbles.
4. Wipe Rims and Apply Lids: Wipe the jar rims clean with a damp cloth, then place the lids and rings on the jars, tightening them fingertip-tight.
5. Process in Boiling Water Bath: Place the jars in a boiling water bath canner, ensuring they are covered by at least 1 inch of water. Process for 35 minutes for pint jars and 40 minutes for quart jars (adjust processing time based on your altitude).
6. Cool and Check Seals: Carefully remove the jars from the canner and let them cool completely on a towel-lined surface. Check the seals by pressing down on the center of each lid; if it doesn't flex, the jar is properly sealed.

2. Drying (Tomato Leather):

1. Spread Tomato Paste: Spread the tomato paste thinly and evenly onto parchment paper or a silicone baking mat.
2. Dry: Dry in a dehydrator at 135°F (57°C) or in an oven at the lowest possible temperature (ideally below 200°F or 93°C) with the door slightly ajar to allow moisture to escape. Drying time can vary from 4 to 12 hours, depending on the thickness and moisture content.
3. Check for Dryness: The tomato leather should be pliable but not sticky.
4. Store: Cut the tomato leather into strips or pieces and store in an airtight container in a cool, dark place.

Pro Tip:

When canning, always use tested recipes and follow recommended processing times to ensure food safety. Improper canning can lead to botulism, a serious and potentially fatal illness.

✳️ Additional Notes:* Always inspect canned goods for signs of spoilage (bulging lids, unusual odors) before consumption.* Dried tomato leather can be rehydrated with water or broth before use.
