Blackberry Blueberry Jam

Jump to Recipe

Blackberry and Blueberry Jam is perfect for baked goods and summer treats

Preserving food is something that goes far back in my family; as far back as it does with most families from central Pennsylvania. Past generations grew up in this area with little money, so producing food was a necessity. Families would go hunting for protein and summer gardens were the main source of produce for the year.

In my own family, my grandparents and all of their children knew how to can and dry the produce grown from their own gardens. In fact, my grandmother’s Mason and Bell jars still float around our kitchens! Jam and jelly recipes have been passed down as well: peach and strawberry preserves are family favorites. This Blackberry Blueberry Jam offers a new twist to the classic berry jams that were made in midsummer, when the vines of wild blackberries and raspberries would bend under the weight of their fruit.

Mixing berries in jams and jellies is nothing new, but adding lemon and lavender gives these preserves a special twist to a classic recipe. Lavender adds a delicate, elegant touch to the fruits. Other flowers could be infused into the jam such as dandelions, violets, or even white clover blossoms would be great as well!

We always encourage you to play with our recipes and make them your own. Try adding in other fruits, or infuse different blossoms into your recipe. Here are some ideas to get you started:

  • A little grapefruit or orange would add brightness to this jam
  • Mix in raspberries

  • Use Blackberry or Blueberry Eastern Shore Honey
