Blueberry Jam Without Pectin

This blueberry jam without pectin is a simple homemade jam made with just blueberries, sugar, and lemon juice. A small batch recipe that lets the fruit's natural flavor shine!
Prep Time 5 minutes
Cook Time 30 minutes
Canning Time (optional) 10 minutes
Total Time 45 minutes
Serving Size 48 servings (3 cups)

Ingredients

  • 4 cups blueberries
  • 2 cups white sugar
  • 3 tablespoons lemon juice

Instructions

  • Put the blueberries and lemon juice in a large pot and gently bring to a simmer over low heat.
  • When the blueberries have released their juices, mash them with a potato masher for a smoother jam (optional), then add the sugar and turn the heat up to medium-high.
  • Cook until your jam reaches the gel stage, about 20 minutes.
  • Pour the jam into your prepared jars, leaving 1/4 inch headspace. Let the jars cool and then store in the fridge. Or, for long-term storage, process in a water bath canner to make it shelf-stable.

Canning Instructions

  • To preserve your blueberry jam, ladle the jam into your prepared canning jars, leaving 1/4 inch of headspace. Wipe the rims clean, and place the lids on finger-tight.
  • Process in a water bath canner for 10 minutes. Then turn off the heat and let the jars cool in the canner for 5 minutes, this helps to prevent siphoning. Then remove them and place the jars on a towel.
  • After 24 hours, check the jars to make sure they have sealed. Any jars that didn't seal, place into the fridge to use up first.

Notes

  • This recipe can be doubled, but don't cook more than 8 cups of blueberries at a time, or it won't set properly.
  • If you are over 6,000 feet in elevation, process for 15 minutes in a water bath canner.
