Whether you're a fan of sweet jams, or you're looking for something with a little more tang, this raspberry rhubarb jam is a perfect choice.
This delicious jam features some of my favorite ingredients, including juicy raspberries and tart rhubarb. With its low sugar content, this jam is not only packed with flavor, but it's also kind to your waistline!
I have always loved raspberry jam, but the store-bought jam has so much sugar and preservatives I hated buying it for my family. However, by making my own jam I can control the amount of sugar that goes into it.
The rhubarb gives it a slight tart taste, and the raspberries give it a sweet, fresh taste. I love putting these 2 fruits together! Plus, these ingredients are picked fresh right off our farm, so I know they are organic and have no added chemicals.
Raspberry rhubarb jam is a staple in my house that we enjoy all year long, not just in raspberry season. It tastes so good on Homemade Dinner Rolls or Oatmeal Apple Muffins right out of the oven.
To keep a steady supply, I freeze fresh-picked raspberries and rhubarb in Ziploc bags in the summer and then use the frozen fruit to make enough jam as I need it. Amazingly, we cannot even tell that the fruit is frozen. It just tastes so fresh!
This jam is naturally sweet and tart and full of flavor - and doesn't include any added pectin or preservatives. It is also a great topping on Buttermilk Sheet Pan Pancakes, Crispy Buttermilk Belgian Waffles, and Ninja Creami Vanilla Ice Cream.

📋 Ingredients
Only 4 ingredients are needed to make this delightful jam. If you don't have the fruit in your garden, you can easily find it at your grocery store, fresh or frozen, or at your local Farmer's Market!
- Raspberries, fresh or frozen.
- Rhubarb, fresh or frozen. Cut the rhubarb into small pieces.
- Sugar. I used organic cane sugar.
- Minute tapioca. This is used as the thickener for the jam.
🥄 Instructions
Before you begin, make sure to wash jars with hot water.
Next, place raspberries in a large-sized pot.
Next, place rhubarb in the pot.
Next, add sugar to the pot. (Feel free to add the sugar in steps. Taste as you go so you don't make it too sweet).
Finally, add minute tapioca to the pot.
Combine rhubarb, raspberries, sugar, and minute tapioca well.
Place saucepan on the stove or burner. Bring the mixture to a boil over medium heat or medium-high heat. (On my induction cooking surface it needed to be medium-high heat). Boil for 1 to 2 minutes. I use a potato masher to smush up the rhubarb and berries as they cook. Stir often to prevent burning.
Reduce the heat to medium-low and continue to simmer at a low boil for 10-15 minutes, make sure to stir. Continue to simmer until the jam is thickened.
Next, carefully spoon the hot raspberry rhubarb jam into clean, sterilized glass jars. Leave about 1-inch of headspace (leave 1 inch of the top of the jar free).
This recipe will fill 3 pint jars.
Let the jam cool completely, about 2-3 hours. Then place lids on the jar. I store all of my jars in the fridge until they are cold, and then leave 1 jar in the fridge and move the other 2 jars into the freezer.
That's all there is to it!
Enjoy!
📖 Substitutions
- Raspberries: Not a fan of raspberries? Substitute strawberries, blueberries, blackberries, or your favorite fruit. I like to use haskap berries (honeyberries) which make a delicious tasting jam.
- Rhubarb: Not a fan of rhubarb or it's out of season? Try using tart apples. They make a great substitute.
- Sugar: I use organic cane sugar, which I find is much sweeter, therefore I only need to use half the amount of sugar called for in a recipe. You could also use Agave Syrup. For every cup of sugar your recipe calls for, try ⅔ cup of Agave Syrup. You could also try white sugar, coconut sugar, or honey.
- Minute tapioca: I use this as it contains no fat or cholesterol, which makes it a healthier choice. However, you could substitute cornstarch. Use 1 tablespoon of cornstarch for every 1 ½ teaspoons of tapioca.
📖 Raspberry jam variations
You can change the flavor of this jam by adding a few ingredients. Some fun ones to try are:
- Ground cinnamon
- Ginger, ground, or fresh.
- Chia seeds.
- A splash of lemon juice to boost the flavor.
- Vanilla extract for a richer flavor.
- Fresh mint for added flavor.
Whatever variation you decide to try, the end result is sure to be absolutely delicious! Be sure to check out my Low-Sugar Strawberry Jam.

At the beginning of this recipe you quote Servings: 3 half pints, then in the body of the recipe, the instruction is to fill 3 pint jars.
What is the correct yield (it's certainly not servings, by the way) ? 3 half pints or 3 whole pints.
