This sweet, fruity homemade strawberry blueberry jam is the perfect addition to your breakfast or snack plate!
Canning jam is not only flavorful and delicious, it’s a great way to preserve the season’s bounty. If you’re in the mood for something more savory, you might check out my canned tomato recipe, Bruschetta in a Jar, from last year.
But this strawberry blueberry jam is a sweet way to kick off the warm weather season. This one is particularly pretty with robust color and flavor. Plus, it’s actually easy to make. I’ll show you how!
You will need
A combination of fresh strawberries, blueberries, blackberries or raspberries
Ball® RealFruit™ Classic Pectin
6 (8 ounce) Ball® half pint jars
Saucepan or stock pot for cooking the jam
Ball® Water Bath Canner or a large, deep stock pot with a lid and rack
Jar lifter and headspace checker
Clean kitchen towels
Make the mixed berry jam
This recipe requires a few specific steps. Follow along closely. If it’s your first time canning jam on your own, it may take a little extra time as you check and double check each step – at least that’s my experience.
The more often you make homemade jam, the more confident you’ll become and the quicker you’ll get through the process.
To make this jam, we’re using the water canning method.
Before starting, wash your fruit and gather all of the necessary supplies including your jars and lids, jar lifter, headspace tool and towels.
If you’re using strawberries, roughly slice large or particularly firm berries to make it easier to crush the fruit. You might do the same with blackberries. Blueberries and raspberries can be mashed whole.
I used a potato masher to crush the berries in a bowl. You can do this in the stockpot to save on clean up!
NOTE: To get the 4 cups of crushed berries, I used 1 quart strawberries and 2 pints of blueberries.
What are the best berries for mixed berry jam?
You can use your favorite berries for homemade jam. I say go with what’s in season and the ones that taste best when you go to the market.
I chose strawberries and blueberries because they are in season and growing locally this month. Blueberries are quite plentiful in Georgia in the summer so I love using them for jam. Plus the color is amazing!
If you are in the Pacific Northwest, for example, you might use blackberries and raspberries right now or some combination of these four.
Bottom line: Use the berries you like and those that are available to you. It’s the perfect recipe for using up berries before they go bad. We know they don’t last long.
Do I have to use all that sugar?
Yes. This recipe has been tested using the sugar and pectin amounts listed. It’s got the right balance of flavor and will set up properly.

How to serve this jam
This jam pairs beautifully with many foods. You can use it as a sweet spread on sandwiches, blend with oil, vinegar and herbs for a fruit vinaigrette, or add to fish, chicken or pork for a fruity topping!
You can eat this mixed berry jam on toast or…
- Make your own fruit on the bottom yogurt.
- Swirl it into oatmeal.
- Add a fruity dollop to a cheese board. It will be especially delicious paired with goat cheese or sharp cheddar.
Got extra jam? Tie on a bow and share as a simple gift for your neighbors!
That last idea is especially useful after you go berry picking this spring and summer.
