Method
- Wash the red bell peppers and jalapeños thoroughly under cold running water. Cut each pepper in half, remove the stem and seeds, and roughly chop the flesh into 1-inch pieces so they blend smoothly.
- Place the chopped peppers in a food processor and blend until completely smooth, working in batches if needed. The goal is a uniform, seedless puree with no visible chunks.
- Pour the pepper puree into a fine-mesh strainer set over a bowl and let gravity do the work for at least 10 minutes to remove excess liquid and any small seeds or fiber.
- Pour the strained pepper puree into your large pot and add the sugar, vinegar, salt, and black pepper. Stir well to combine everything evenly before heating.
- Place the pot over high heat and stir frequently until the mixture comes to a rolling boil that you cannot stir down; this typically takes 15 to 20 minutes.
- Once the mixture is at a full rolling boil, quickly stir in the liquid pectin and return the mixture to a rolling boil. Let it boil for exactly one minute, stirring constantly, then remove from heat immediately.
- Skim off any foam that has risen to the surface using a spoon. Using a funnel and jar lifter, carefully fill sterilized half-pint jars leaving 1/4 inch headspace, then wipe the rims clean with a damp cloth.
- Place the filled jars into a water bath canner with enough water to cover the lids by at least one inch. Bring the water to a rolling boil and process for 10 minutes, then turn off the heat and let the jars sit in the water for 5 minutes before removing them.
Notes
Do not skip the straining step to ensure a firm jelly without weeping. Use a candy thermometer to verify the mixture reaches 220°F before adding pectin. Sterilize jars properly and allow sealed jars to cool 24 hours before storage.
