*If making jelly to preserve fruits/vegetables and not for immediate use, prepare water-bath canner, jars and lids according to manufacturer’s instructions.
Start by washing and finely dicing all peppers (either with a knife or food processor), making sure to remove the ribs and seeds. Lightly sauté in a large stock pot over medium heat.
Once the peppers have turned almost translucent (3-5 minutes), add tangerine purée, lime juice, and vinegar to the mixture and stir well to combine.
Stir in the pectin next. Increase the heat to medium-high and bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred), stirring constantly for 5-10 minutes.
Stir in the sugar. Return to full rolling boil for exactly 1 min., stirring constantly. Remove from heat, skimming off any foam with metal spoon (if necessary).
Ladle immediately into prepared jars, filling to within 1/4 inch of tops.
