  • Tip 1: Once the blueberries heat enough that the juice leaks out and the juice starts to bubble, it will take about 20 minutes to cook down to a jam.
  • Tip 2: Mash the blueberries slightly once they start to soften. I like to use a potato masher. Then, mash the blueberries in the middle of cooking process again.
  • Tip 3: The recipe makes just under 1 1/2 cups of jam. If you have more, cook it down more until it is 1 1/2 cups. If you want a thicker jam, cook it to 1 1/4 cup to 1 cup.
