This Strawberry Blueberry Jam recipe is one of my favorite flavors of homemade jam to make. It's a toss up between this mixed berry jam canning recipe and my Jalapeno Pepper jam recipe when it comes to my all time favorite flavor of homemade jam.

This Strawberry Blueberry Jam recipe tastes great on a fresh baked biscuit or on toast in the morning but one of my favorite ways to eat Strawberry Blueberry Jam is as an ice cream topping. I love to drizzle a tablespoon of this mixed berry jam over a bowl of vanilla ice.

How To Make Homemade Strawberry Blueberry Jam or Mixed Berry Preserves

Are you looking for a new summer treat to add to your pantry? Look no further! Our homemade strawberry and blueberry jam recipe is the perfect addition. With just a few easy steps, you can create a delicious and flavorful jam that will impress everyone who tries it. So why not give it a try? Your taste buds will thank you.

Strawberry Blueberry Jam Ingredients

  • 4 cups sliced strawberries, mashed
  • 4 cups fresh blueberries, mashed
  • 7 cups sugar
  • ½ tablespoon butter or margarine (optional)
  • 3 ounce pouch liquid Fruit Pectin

Canning Supplies Needed

  1.  8 half pint canning jars, new unused wide mouth flat lids and bands
  2. Large pot to use for a Hot Water Bath Canner or one of my recommended electric Hot Water Bath Canner Options below
  3. Wide Mouth Funnel
  4. Jar Lifter
  5. Canning Ladle
  6. Paper towels
  7. Dissolvable Labels (optional) can use a sharpie but the labels are really pretty
  8. Progressive 3-Piece Canning Essentials Kit includes a wide mouth funnel, jar lifter and magnetic lid lifter

My favorite canning jar for jams and jellies is the Kerr® Wide Mouth half-pint 8 oz mason jars. I love the short squat shape and the wide mouth makes it very easy to fill. I have a large collection of canning jars and usually will use whichever canning jars are easily available (not packed away in the garage).

Strawberry Blueberry Jam Directions

  1. Prepare your jars and lids by washing in hot soapy water. Check for cracks or chips and discard any damaged jars.
  2. Prepare a large hot water bath canning pot that is large enough to submerge all of your jars in at once.
  3. Fill Hot Water Bath canning pot half-full with water and add jars. Add more water if needed to allow for the water to be 2 inches over all the jars. Bring the water to to a boil then reduce the heat and allow the jars to sit in the simmering water.
  4. Alternately if using an electric canning system follow the instructions from the manufacturer to prepare your canning jars.
  5. Wash the strawberries, drain well and stem. Slice them and measure them until you have 4 cups of sliced strawberries. Crush the strawberries in a large bowl and set aside.
  6. Place the blueberries in another bowl and crush, leaving some whole berries.
  7. Add the 7 cups of sugar to a large pot.
  8. Measure 4 cups of the crushed strawberries and pour into the pot with the sugar.
  9. Measure 4 cups of blueberries and pour into the pot with the strawberries and suagr.
  10. Turn the heat on low and add the butter to the pot to help reduce the amount of foam that will form on the top of the pot.
  11.  Stir to mix the sugar with the crushed berries.
  12. Once most of the sugar has dissolved increase the heat to high and bring to a full rolling boil (a boil that doesn't stop bubbling when stirred), stirring constantly to prevent scorching.
  13. Stir in pectin once heated to a full rolling boil. Return to a full rolling boil and boil for exactly 1 minute, stirring constantly.
  14. Remove the pot from heat and allow to settle for a few minutes.
  15. Skim off as much foam as possible with metal spoon and discard the foam.
  16. Remove one jar from the hot water bath canner and place upside down on a soft towel to drain for a few seconds. Carefully flip the jar right side up using a towel to protect your hands from the hot jar.
  17. Place the wide mouth funnel in the top of the warm jar and ladle the hot jam into the hot jar, filling to within ¼ inch of the top. Wipe the jar rim and threads with a damp paper towel.
  18. Place a flat lid on top of the jar then screw a band on the jat just until finger tight.
  19.  Place the filled jar on a folded towel as you continue to fill each of the jars with jam.
  20. Once all of the jars are filled with jam place them on an elevated rack in your hot water bath canner.
  21. Carefully lower rack and jars into canner. (Water must cover jars by at least 2 inches. Add boiling water to the pot to bring the level up, if needed.)
  22. Cover the pot; bring water to gentle boil and place a lid on the pot. Process the jam jars for 10 minutes. Carefully remove the jars from the hot water bath with a jar lifter and place upright on a towel to cool completely overnight.
  23. You should begin to hear the magical pinging of your jars sealing as they cool.
  24. After the jars are cool, check seals by pressing the middle of the lid with a finger. (If lid springs back, lid is not sealed properly and the jam will not be able to be stored in a cabinet or pantry. You can refrigerate any jars that do not seal to eat immediately.
  25. Refrigeration is necessary for jars that have not sealed properly.
  26. Write the name of the jam and the date the jam was made on a label and apply to the jar. Alternately you can write this information with a Sharpie permanent marker on the flat lid.
  27. Jam jars that have sealed properly can be stored in a cool dry cabinet or closet for up to one year.
  28. Discard jam or jelly after the one year canned date.

Pro Canning Tips

  • Mix Berries Thoughtfully: When combining strawberries and blueberries, consider the flavor balance. Strawberries are naturally sweeter, while blueberries can offer a subtle tartness.
  • Mash or Leave Whole: Decide whether you prefer a smoother jam with mashed berries or a chunkier consistency with whole blueberries left in the mix.
  • Sugar: Do not alter the amount of sugar called for in jam recipes or the jam will not set properly.
  • Simmer Slowly: Cook your berry mixture on a low heat to prevent burning and allow the flavors to develop fully.
  • Skim the Foam: As the jam cooks, a foam may form on the surface. Skim this off with a spoon to ensure a clear, attractive jam.
  • Fill Jars to the Correct Level: Leave a ¼ inch of headspace at the top of your jars to allow for expansion during the sealing process.
  • Store Wisely: After sealing, store your jam in a cool, dark place. Once opened, keep it refrigerated to maintain freshness. Homemade strawberry and blueberry jam should be consumed within a few weeks after opening.

    I had frozen strawberries from the Willamette Valley and Olympic blueberries from Gibson Farms in Siletz. This was excellent, will be keeping most but giving several away. Great combination!

    This is a fantastic recipe. I loved how she described what to look for. You kind of know where you are at. The fruit gives it enough sweetness, so not alot of sugar added. It was so good! I wish there was a way to share my picture of how it came out.
