¾ cup granulated sugar
1 tablespoon fresh lemon juice

Cook Mode Prevent your screen from going dark

Instructions

Place a small plate in the freezer for testing consistency later.
In a wide skillet or heavy-bottomed pan, combine blueberries, sugar, and lemon juice.
Cook over medium-high heat, stirring often, until mixture reaches a vigorous rolling boil.
Maintain a rolling boil for 10 minutes, stirring regularly to prevent scorching.
Test doneness by dropping jam on the chilled plate—jam should move slowly like thick honey.
Remove from heat and transfer to sterilized jars or heat-proof containers. Cool completely before storing.

Notes

Use fresh or thawed frozen blueberries. Wild blueberries contain more natural pectin for faster thickening. Always use the frozen plate test to ensure the perfect consistency. Sugar can be substituted with maple syrup or coconut sugar, but this may affect preservation.
