  • This easy jam needs just 4 ingredients.
  • There is no pectin needed to make this jam, so no need to run out to the store.
  • This is so easy to make, simply chop and simmer.
  • This jam will keep for 2 weeks and can also be frozen for up to 6 months.

Use this jam to spread on morning toast, scones, or biscuits. Or make some classic thumbprint cookies.

Ingredients in Strawberry Rhubarb Jam

Strawberries – Use fresh strawberries when possible, spring and early summer are the seasons of everything berry. If making jam in the off-season and fresh berries aren’t available, frozen berries will work but will need a bit of extra cooking time.

Rhubarb Rhubarb is another one of those spring vegetables. Those long pink slender stalks are a tart companion to the sweet strawberry. Frozen rhubarb works just as well in this recipe.

Sugar – We use granulated sugar for this recipe and haven’t tried it with substitutions or other sweeteners. When boiling, the sugar almost ‘candies’ which thickens the jam.

Lemon Juice – Just a little spoonful is all that is needed, you can substitute with a teaspoon of vanilla extract if you’d like.

How to Make Strawberry Rhubarb Jam

Homemade jam made with sweet fried berries and rhubarb is a sweet summer treat.

  1. Bring the rhubarb, sugar, and lemon juice to a boil in a saucepan.
  2. Reduce heat and let simmer.
  3. Add the strawberries and continue to cook (per the recipe below).

Remove from stove and let cool before serving with your favorite scones or on toast!

Sweet as Sugar

This recipe makes a sweet jam with a thick consistency, as we think jam should be! Boiling the fruit and sugar is what makes it set up well.

We tried it with varying amounts of sugar. With less sugar, the mixture still thickens but the texture becomes more like fruit spread than jam.

Tips for the Best Jam

For jam to thicken properly (especially without the pectin), it needs to cook long enough. There should not be much liquid remaining in the pot.

In order to set up, the jam needs to reach 220°F on a thermometer or check it using the plate method below.

If you don’t have a thermometer, test a small amount of jam on a cold plate. Place a glass/ceramic plate in the freezer for 5-10 minutes. Add a large spoonful of jam to the chilled plate and let it sit for a couple of minutes. The jam should set to a thick consistency, if it does not, simmer for an additional 5-10 minutes and check again.

  1. This looks a good recipe but I wonder why does it only keep for 2 weeks in the refrigerator? How does it differ from regular jam that lasts much longer?
    Thank you.

    1. Hi Lynne, we recommend 2 weeks to keep the flavour the freshest. When it comes to store bought jam, there are preservatives that help it stay fresh longer.

  2. I made this recipe this morning because I had extra rhubarb and strawberries on hand. Delicious! 5 small jars and a medium jar in my freezer. Will be enjoying those this winter.5 stars

    1. I am so glad you enjoyed this recipe Claire! Such a treat to be able to enjoy throughout the winter.

  3. Holly, How would I go about canning this recipe for long term. It’s looks amazing and I have 2 large rhubarb plants.
    Thank you so much for all your wonderful recipes and beautiful pictures.

    1. I have not tried canning this recipe so I can’t say for sure Anita. If you try it I would love to hear how it turns out!

      I am so glad you are enjoying the recipes!

  4. What type of container do you find works best for storing in the freezer? I know you recommend air tight, but that can mean a lot of things.

    1. I store jam in mason jars in the freezer, but be sure to leave about an inch of room in the jar for expansion.

  5. The jam was very easy to make and tastes yummy. I did not change the recipe, I should have doubled everything. It’s a keeper

    1. Yes, you can but as mentioned in the post, this will change the texture from jam to more of a fruit spread. We tested this with sugar as low as 1 cup. You may also need to increase the cooking time.

      I would suggest using the ‘cold plate’ method mentioned in the post to check how the jam will set up.

      1. Sorry about that, Holly. I noticed it in the post AFTER I submitted lol. I tried it with 1 cup sugar and to be honest it came out AMAZING! Consistency and all! Thanks for all you do xo

  6. Hi Hollie , I love your recipes! I was wondering in the rhubarb/ strawberry jam I would be using frozen since I don’t have access to fresh. Do I let the rhubarb thaw first or use frozen and does it have to cook longer? Thanks, Carol
