Key Ingredients & Their Roles
- Rhubarb: Provides a tangy base; ensure it’s fresh for the best flavor.
- Sugar: Sweetens and helps achieve that perfect jam consistency; can be adjusted based on taste.
- Lemon Juice: Adds acidity which brightens the flavor; fresh squeezed is always best for brightness.
- Optional Spices: A hint of cinnamon or ginger can add a warm undertone.
How to Make Rhubarb Jam
- Begin by placing the rhubarb in a large glass bowl. Sprinkle the sugar over, stirring well to coat. Let it sit covered for at least 8 hours, stirring once or twice. This draws out the juices and begins the maceration process.
- Once the rhubarb has released its juice, transfer the mixture into a nonreactive pot. You should see a nice sweet syrup forming already.
- Stir in the fresh lemon juice and bring the mixture over medium-high heat. Cook until it reaches a gentle simmer, which takes around 20 minutes. Keep stirring frequently to ensure even cooking.
- After achieving a simmer, reduce the heat to low and let it cook for another 10 minutes. You’ll notice the jam thickening—this is your cue to remove it from heat.


Pro Tips & Troubleshooting
- When I first made the jam, I found that letting the rhubarb sit overnight brought out even more flavor!
- A common pitfall is not stirring enough; burning can happen if the heat is too high. Just keep it on a gentle simmer.
- For a flavor twist, consider adding a few sprigs of fresh mint during cooking for an aromatic touch.
- Scaling this recipe is easy; just double or halve the quantities, keeping the same cooking times!
Storage & Make-Ahead Guide
This Rhubarb Jam can be stored in the fridge for up to 3 weeks, or frozen for up to 6 months. I found that freezing in smaller jars helps with portion control while ensuring maximum freshness. For thawing, simply place in the fridge overnight, or warm gently on the stove if you prefer it spreadable.
What to Serve With Rhubarb Jam

Frequently Asked Questions
- How can I tell when the jam is done? The jam should be thick and glossy, with a noticeable reduction in volume.

- What if the jam is too runny? Simmer it longer uncovered to evaporate some of the liquid.
