Transform your seasonal rhubarb harvest into a delightful jam that can be enjoyed year-round. This simple recipe combines the tartness of rhubarb with the sweetness of sugar and a hint of lemon juice to create a perfectly balanced spread.
If you're not familiar with rhubarb, it is a tart, celery-like vegetable often used in desserts. You can find it in the produce section of most supermarkets, especially during the spring and early summer. Make sure to select stalks that are firm and brightly colored. Lemon juice is usually available in the juice aisle or produce section.

Ingredients For Rhubarb Jam Recipe
Rhubarb: A tart, celery-like vegetable that adds a unique flavor to the jam.
Sugar: Sweetens the jam and helps it to set properly.
Lemon juice: Adds acidity to balance the sweetness and helps in the preservation process.
Technique Tip for Rhubarb Jam
When making rhubarb jam, it's crucial to keep a close eye on the simmering process. Stir frequently to prevent the sugar from caramelizing too quickly and to ensure the rhubarb breaks down evenly. If you notice the mixture thickening too fast, you can add a splash of water to maintain the right consistency. This will help achieve a smooth, spreadable jam.

How to Store or Freeze Rhubarb Jam
- To store your delightful rhubarb jam, ensure the jars are properly sealed and cooled. Place them in a cool, dark pantry or cupboard. This will keep your jam fresh for up to a year.
- For a more immediate treat, refrigerate the sealed jars. The rhubarb jam will stay fresh and delicious for up to three months.
- If you prefer to freeze your jam, pour it into freezer-safe containers, leaving about half an inch of space at the top to allow for expansion. Seal the containers tightly.
- Label each container with the date and contents. This helps you keep track of your rhubarb jam and ensures you use the oldest batches first.
- When you're ready to enjoy your frozen jam, thaw it in the refrigerator overnight. This gradual thawing process helps maintain the jam's texture and flavor.
- For a quicker thaw, place the sealed container in a bowl of cold water. This method is faster but still gentle on the rhubarb jam.
- Once thawed, give the jam a good stir to reincorporate any separated liquids. Enjoy your rhubarb jam on toast, in desserts, or straight from the jar!
How to Reheat Leftovers
- Place the rhubarb jam in a small saucepan over low heat. Stir occasionally until warmed through, being careful not to let it boil.
- Microwave the jam in a microwave-safe bowl. Heat in 15-second intervals, stirring in between, until it reaches the desired temperature.
- For a more even reheating, use a double boiler. Place the jam in a heatproof bowl set over a pot of simmering water. Stir gently until warmed.
- If you prefer a more rustic method, place the sealed jar of rhubarb jam in a pot of warm water. Heat over medium-low heat until the jam is warmed through.
