🌶 Jalapeño Pepper Jelly

This spicy jelly is a fun one to keep in the pantry. It can be made in 1/4 pint or half-pint mason jars, making it a good size for gift giving, too.

Ingredients

Jalapeno peppers – You’ll need a scant 1/2 pound of peppers to make this recipe. You can safely substitute any type of hot peppers for the jalapeños. 

Bell peppers – You can use green peppers or red bell peppers. For this batch, I obviously opted for green. One large pepper will net the required amount. 

Sweetener – I used sugar for this recipe, but you can opt to use honey as well. The quantities differ a bit, so be sure to check the notes in the recipe card below. 

Vinegar — Use white vinegar or apple cider vinegar, either one is fine. Be mindful of this little tidbit when buying apple cider vinegar.

Pectin – This recipe is made using Pomona’s Universal Pectin. This is the only pectin I use anymore as it allows me to use much less sweetener. The standard pectin brands and liquid pectin use an obscene amount of sugar in my opinion, often requiring equal amounts of sugar and fruit!

Making the Jelly

This recipe is for water bath canning because the resulting jalapeno pepper jelly is acidic, with a pH of about 3.0.

Start by finely dicing the peppers. You can chop peppers by hand or with the help of a food processor. Avoid over-processing; you don’t want a pepper puree! 

No matter which method you use, be mindful that the jalapenos can cause skin irritation; avoid touching your face or eyes.

🍅 Safety First!

Canning is an excellent way to preserve food for the pantry, but there are some important safety considerations to keep in mind. The recipes on this site have been made following safe canning procedures by a certified Master Food Preserver.

  • Know the difference between water bath canning and pressure canning. Low acid items must be pressure canned for safety. 
  • Altering ingredients may change the recipe’s pH, posing a safety issue. I highly recommend investing in pH paper to test your products for acidity level when canning. Note: The Hawaii Master Food Preservers suggest a pH of 4.2 or lower in the tropics. In other regions, the recommended pH is 4.6 or lower.
  • Use the proper jars and lids. Never reuse lids, with the exception of the Tattler or Harvest Right hard plastic lids that are intended for such a purpose.

Canning the Jam

You’ll need special canning jars, lids, and rings (read more about canning equipment here) to make this blackberry jam shelf-stable, but the process isn’t difficult.

Fill the jars of jelly leaving a quarter inch headspace at the tops of the jars. Place the lids on and process them in a boiling water bath. What this means is you’ll put the filled and sealed jars of jam into boiling water and heat them for ten minutes. This assures that the jars will seal well.

Once the jars are filled, you’ll process them in a hot water bath. What this means is you’ll put the filled and sealed jars of jam into hot water, bring to a full rolling boil, and process them for ten minutes. This assures that the jars will seal well and kills potential bacteria and molds. 

Hot tip: Boil some extra water in a saucepan or electric kettle as you’re working. If you need to top off the water in the canner, you won’t cool down the water too much.

Remove the jars to a towel-covered countertop and allow to cool fully. As they cool, you’ll hear the little “tink” sound of the jars sealing. Store any unsealed jars in the fridge and use those first. (This is unusual, but it does happen once in awhile.)

Remove the ring from each sealed jar, rinse to remove any jam residue, and store (without the ring) in the pantry or a cool, dark place.

Small Batch 

This hot pepper jelly recipe nets 3 half-pint jars, which means you don’t have to pull out the full-sized water bath canner. You can cook the jelly in a large saucepan and process the jars in a large pot. Just be sure that it’s deep enough that the jars are covered by 2″ of water.

Canning Jalapeno Jelly

Yield: 3 - 1/2 pint jars
Prep Time: 15 minutes
Cook Time: 30 minutes
Processing Time: 10 minutes
Total Time: 15 minutes

This homemade jalapeño jelly is a great way to preserve fresh jalapeños and a wonderful pantry ingredient to keep on hand for surprise guests.

Ingredients

  • 2/3 cup jalapeño peppers, diced (scant 1/2 pound)
  • 2/3 cup green bell pepper, diced (1 large pepper)
  • 1-1/3 cup distilled vinegar (5% acidity)
  • 2 teaspoons calcium water (see below)
  • 2-1/3 cups granulated sugar, divided
  • 1-1/2 teaspoons pectin (Pomona's)

Instructions

Prepare for Canning

  1. Wash the jars you'll use, making sure each is clean and free of nicks in the rim, which could impede sealing.
  2. Wash canning lids and rings in hot water; set aside.
  3. Prepare the calcium water: Combine ½ teaspoon calcium powder (from the small packet in the box of Pomona’s pectin) with ½ cup water in a small jar. Screw on a lit and shake until well-combined. You'll have more than you need for this recipe. Store the excess in the refrigerator for use in making additional jam or jelly recipes.
  4. Place empty jars in a canning pot or large stock pot with enough water to cover by an inch or two, cover pot, and set on high heat. It can take awhile for the water to heat, so get it started before you begin making the recipe.

Prepare the Jelly

  1. Remove stems and seeds from bell pepper and finely dice. Remove stems from jalapeño peppers; removing seeds and membranes is optional. Leaving them in will add more heat to the jelly. You can chop with a knife or pulse the peppers in a food processor. Measure the peppers after chopping.
  2. Transfer chopped peppers to a large saucepan and add vinegar. Heat to a boil, then simmer for 5 minutes.
  3. While peppers are cooking, combine 1/2 cup of the sugar with the pectin and stir well.
  4. Add calcium water to the hot mixture and stir to combine.
  5. Add sugar and pectin mixture, stirring vigorously for a minute or two to dissolve pectin. Add the rest of the sugar and return to a full boil; remove from heat. 

Process the jars

  1. While mixture is returning to a boil, remove the empty jars from the canner, draining the water back into the pot.
  2. Ladle hot jelly into prepared jars, leaving a 1/4" headspace.
  3. Wipe jar rims to remove any residue. A clean rim is essential to a good seal.
  4. Set jar lids in place. Screw bands on finger tight.
  5. Use a jar lifter to gently submerge jars into hot (180°F) water in the canning pot. Water should cover the top of the jars by two inches. The water will cool somewhat in reaction to the addition of the jars. Return the water to a boil and set the timer.
  6. Process jars for 10 minutes at 0-1,000' feet altitude. Add an additional 1 minute to the processing time for every 1,000 foot above sea level.
  7. Remove jars from water using the jar lifter and transfer to a solid, towel-covered surface. Allow to cool for 12-24 hours.
  8. Check seals. Lids should be solid and pulled down tight. (if they flex and pop, the jar didn’t seal; put unsealed jars in the refrigerator and use those first).
  9. Remove rings and wash outsides of jars. Label and store in a cool, dry place for up to a year.

Notes

Adapted from Pomona's Universal Pectin recipe; made by a certified Master Food Preserver.

You can use 1-1/2 cups honey to replace the sugar in this recipe.

This recipe makes a mildly spicy pepper jelly. If you'd like more heat, you can safely increase the ratio of hot peppers to sweet peppers, maintaining the total amount of peppers at 1-1/3 cups. Peppers are safely interchangeable in canning recipes.

This recipe tested at 3.0 pH, making it a safe recipe for water bath canning.
