Making Sweet and Delicious Blueberry Jam from Scratch


Blueberries are one of the most popular and flavorful fruits in America and making jam from this tangy fruit is a fantastic way to enjoy it all year round. Making a perfect blueberry jam requires a little patience and some precise techniques. In this article, we will show you how to make sweet, tangy and delicious blueberry jam from scratch.

Gather Your Supplies

The first step in making blueberry jam is to gather all the necessary equipment and ingredients. You will need:

  • 6 cups of fresh blueberries
  • 3 cups granulated sugar
  • 1/4 cup fresh lemon juice
  • 1/2 teaspoon butter
  • Canning jars with lids and rings
  • Canning pot or large stockpot with a rack
  • Canning tongs and jar lifter
  • Ladle and funnel
  • Clean dish towels

Cooking the Jam

Once you have gathered all your supplies, it is time to make the jam. Here are the steps to follow:

  1. Clean and sterilize your canning jars and lids by boiling them for 10 minutes.
  2. Rinse and drain the blueberries.
  3. In a large stainless-steel pot, combine the blueberries, sugar, and lemon juice.
  4. Stir the mixture constantly over low heat until the sugar has dissolved.
  5. Increase the heat to medium-high and bring the mixture to a full rolling boil, while stirring frequently.
  6. Add butter to prevent foaming and continue stirring for 10-15 minutes or until the jam achieves the desired thickness.
  7. To test if the mixture has thickened enough, dip a spoon into the jam, and if the mixture falls off in thick clumps, then it is ready.
  8. Remove the pot from the heat and carefully ladle the hot jam into your clean jars using a funnel. Fill the jars to within ¼ inch of the top edge.
  9. Wipe the rim of each jar clean with a clean and damp cloth, put the lids, and twist on the rings firmly.
  10. Lower the jars into a canning pot with the rack submerged into water and process for 10 minutes in boiling water.
  11. Remove the jars from the pot and let them cool for 24 hours before storing them in a cool dry place.

Tips for Perfect Blueberry Jam

  • Use fresh and ripe blueberries for the best flavor and consistency.
  • Boil your canning jars and lids to sterilize them and keep the jam bacteria-free.
  • Don’t overcook your jam, or it will become too thick and taste like candy.
  • Skim the foam off the top of the boiling mixture with a slotted spoon to get a clear and smooth jam.
  • Store your jars in a cool and dry place away from sunlight and heat for an extended shelf life.

In conclusion

Making blueberry jam is not a complicated procedure, and with the right ingredients and techniques, anyone can do it. This homemade jam is not only delicious, but it’s also free from preservatives and other harmful chemicals that are commonly found in store-bought varieties. With this recipe, you can enjoy a fresh and flavorful taste of blueberries all year round.
