In a blender, blend the red bell peppers, jalapeños, and all the vinegar.
Transfer to a ____ L pan, add the pectin, and bring to a boil.
Add the sugar, and return to a rolling boil. Stir constantly, as it will boil over very quickly. Boil for 1 minute, until it reaches 220 °F.
Remove the jelly from the heat, and skim the foam off the top of the jelly.
Using tongs, remove a jar and a lid from their respective pots (filled with hot water).
Ladle the jelly into the jar, until it is about 5 mm from the top of the jar.
Using tongs, place the lid on the jar, and secure it in place using a clean ring. Tighten well.
Using tongs, transfer the jar back to the pot with hot water.
Repeat this process for all the jars. If the last jar that cannot be filled to within 5 mm of the top, do not put the jar back in the hot water. Put it aside to cool, and later store it in the refrigerator.
Bring the pot back to a boil, and boil for 5 minutes. Remove the jars from the pot, and allow them to cool. You should hear the lids "pop" as they cool, and the lids are pulled inwards (concave). There is no need to wipe excess water from the jars, as it will evaporate on its own.
