Vegetables must be canned in a pressure canner for the correct time and pressure (PSI) to ensure their safety. If not canned correctly, these low acid foods may contain the deadly botulism toxin.
Vegetables may be canned without salt. Salt adds flavor but does not prevent spoilage. If you use a weighted-gauge canner and can at an altitude less than 1000 feet, you may use 10 PSI instead of 15 PSI for the canner pressure. This will improve nutrient and quality retention of the vegetables. Check with your local county extension office or Soil Conservation District for altitude information.
Recipe (hot or sweet including chilis, jalapeno, and pimiento)
Quantity: An average of 9 pounds is needed per canner load of 9 pints. A bushel weighs 25 pounds and yields 20 to 30 pints – an average of 1 pound per pint.
Quality: Select firm yellow, green, or red peppers. Do not use soft or diseased peppers.
Procedure: Select your favorite pepper(s). Caution: If you choose hot peppers, wear plastic gloves while handling them or wash hands thoroughly with soap and water before touching your face. Small peppers may be left whole. Large peppers may be quartered. Remove cores and seeds. Slash two or four slits in each pepper, and either blanch in boiling water or blister using one of the following methods:
Oven or Broiler Method: Place peppers in a hot oven (400° F) or broiler for 6-8 minutes until skins blister.
Range top Method: Cover hot burner, either gas or electric, with heavy wire mesh. Place peppers on burner for several minutes until skins blister.
Allow peppers to cool. Place in a pan and cover with a damp cloth. This will make peeling the peppers easier. After several minutes, peel each pepper. Flatten whole peppers. Add 1/2 teaspoon of salt to each pint jar, if desired. Fill jars loosely with peppers and boiled water, leaving 1 inch headspace. Adjust lids and process.
