Ingredients
- 8 cup blackberry, rinsed and partially crushed
- 3 lemon seeded and chopped into pea-size chunks
- 2 pack pectin
- 1 tbsp butter
- 1/3 cup sugar, divided
Directions
Place the blackberries and lemons in a nonreactive pot with the pectin and butter, and bring to a strong boil. Add half the sugar. When the mixture shows further signs of beginning a second boil, add the remaining sugar and bring to a fierce rolling boil. Begin timing for 2 minutes and then watch for signs of jelling. Depending on the water content in the berries, jelling signs may take longer.
When ready, ladle into sterile jars, seal, and invert for 2 minutes only.
