Love blueberries, but never made jam. Wonder how it'll be.

Ingredients (6 half-pints)

• 7 cups blueberries
• 4 cups sugar
• ⅛ tsp salt
• 1½ tsp lemon zest
• ¼ cup lemon juice

Directions

1. Add half the washed blueberries to a stockpot and crush them with a potato masher.
2. Stir in the rest of the berries, the sugar, salt and zest. Cover and bring to a simmer or low boil, stirring frequently.
3. Uncover and cook for 25 minutes, stirring every 5 minutes. Test for gel stage on a plate in the freezer.
4. Pour jam into prepared canning jars, leaving ¼" headspace. Process in a water bath canner for 10 minutes.
