Pepper Jelly

My friend Lisa, introduced me to her yummy Pepper Jelly a while back. She cans it several tims a year and it is such a yummy appetizer. She got the recipe from the cookbook Putting Up by Stephen Dowdney, but altered it a little bit. Each batch makes about 17-18 half pints. I like it served best over cream cheese and eaten with Ritz/Townhouse crackers.

2 1/2 c very small diced red peppers, seeds removed
2 1/2 c very small diced green peppers, seeds removed
3/4 c fine diced jalapeno peppers, seeds removed
3 c cider vinegar
13 c sugar
1 Tbsp butter
1-2 Tbsp red pepper flakes depending on how hot you want it
2 pack liquid pectin Certo brand, found in the canning section or by the Jell-O

Bring all ingredients except pectin to a rolling boil. Add pectin and return to a boil. Time for 1 1/2 minutes and take off burner. Hot pack in warm jars for 15 minutes. Remove from canner and allow to cool for 24 hours. The jelly will set up as it cools.
