Blue Berry Lime Jam Recipe
Yields: about 6 half-pints
4 1/2 cups or blueberries
6 tablespoons classic pectin
5 cups or sugar
1 tablespoons grated lime peel
1/3 cup lime juice
Crush blueberries on layer at a time. Combine crushed blueberries and classic pectin in a large sauce pot. Bring to a boil, stirring frequently. Add sugar, stirring until dissolved. Stir in grated lime peel and lime juice. Return to a rolling boil. Boil hard 1 minute, stirring constantly. Remove from heat. Skim foam if necessary. Ladle hot jam into hot jars, leaving 1/4 inch headspace. Adjust two-piece caps. Process 15 minutes in a boiling-water canner.
Tips:
1. We used a potato masher to crush the blue berries. I think next time I might use a food processor, because I do not like pieces of fruit in my jam.
2. Jam will burn if you boil too long!
