Canning Instructions for Jalapeno Pepper Slices

Every jar of home-canned food is like a little gift to your future self, filled with the taste of sunshine and hard work.


Here are step-by-step canning instructions for jalapeno pepper slices from the Ball Blue Book:

Ingredients and Equipment:

  • Fresh jalapeno peppers
  • Vinegar (5% acidity)
  • Canning jars, lids, and bands
  • Water bath canner
  • Jar lifter
  • Lid lifter/magnetic wand
  • Gloves (optional, but recommended when handling hot peppers)
  • Cutting board and knife

Instructions:

1. Prepare Your Equipment:

  • Wash jars, lids, and bands in hot, soapy water and rinse well.
  • Inspect jars for cracks and chips. Discard any defective ones.
  • Place jars in the canner filled with water, bring it to a simmer (180°F/82°C), and keep them hot until ready to use.
  • Put lids in a small saucepan, cover with water, and bring to a simmer. Keep them simmering until ready to use.

2. Prepare Peppers:

  • Wear gloves to protect your hands from the heat of the peppers.
  • Wash jalapeno peppers thoroughly.
  • Remove stems from peppers.
  • Slice peppers into rounds, discs, or strips, depending on your preference. You can also leave them whole if desired.

3. Heat Vinegar Solution:

  • In a large saucepan, combine vinegar with water in a 50:50 ratio (for example, 1 cup of vinegar to 1 cup of water). Use enough to cover the peppers.
  • Bring the vinegar solution to a boil.

4. Fill Jars:

  • Pack sliced jalapeno peppers tightly into hot jars, leaving 1/2-inch headspace.

5. Pour Vinegar Solution:

  • Carefully ladle hot vinegar solution over the peppers, maintaining the 1/2-inch headspace.

6. Remove Air Bubbles and Adjust Headspace:

  • Insert a non-metallic spatula or chopstick into the jar, gently press against the peppers to release any trapped air bubbles.
  • Add more peppers or vinegar solution if necessary to maintain proper headspace.

7. Wipe Jar Rims:

  • Use a clean, damp cloth to wipe the rims of the jars to remove any residue or drips.

8. Apply Lids and Bands:

  • Using a lid lifter or magnetic wand, remove lids from the simmering water and place them onto the jars.
  • Screw on bands fingertip tight. Do not over-tighten.

9. Process Jars:

  • Place filled jars into the canner rack, ensuring they are covered with at least 1-2 inches of water.
  • Bring water to a full rolling boil.
  • Process jars for 10 minutes.

10. Remove Jars and Cool:

  • Once processed, turn off the heat and let the jars sit in the canner for 5 minutes.
  • Using a jar lifter, carefully remove the jars from the canner and place them on a towel or cooling rack.
  • Allow jars to cool undisturbed for 12-24 hours.

11. Check Seals:

  • After cooling, check the seals by pressing down on the center of each lid. If the lid doesn’t flex, the jar is sealed.
  • Any unsealed jars should be refrigerated and used promptly.

12. Label and Store:

  • Label each jar with the contents and the date processed.
  • Store jars in a cool, dark, dry place.
  • Use within a year for best quality.
