Ingredients You’ll Need
- 3 cups chopped rhubarb: About 4-5 medium stalks, cut into approximately 1/2-inch pieces. Fresh rhubarb gives a vibrant flavor, but if fresh isn’t available, frozen works too.
- 3/4 cup granulated sugar: This helps to balance the tartness of the rhubarb. If you’re watching your sugar intake, consider substituting with honey or maple syrup—just adjust to taste.
- 1 1/2 tablespoons lemon juice: Freshly squeezed works best, enhancing the preserves with a refreshing zest.
- 1 teaspoon vanilla extract: This adds a lovely aromatic note that complements the fruitiness of the rhubarb.
How to Make Rhubarb Preserves
Chill Your Plate: Place a small plate in the freezer before you start cooking. This will help you test the preserves’ doneness later on.
Prep the Rhubarb: In a 3-quart or larger saucepan, add the 3 cups of chopped rhubarb, 3/4 cup granulated sugar, and 1 1/2 tablespoons of lemon juice. Stir them together to ensure that the rhubarb is coated with sugar.
Boil the Mixture: Bring the mixture to a boil over medium-high heat, stirring frequently. You want to keep an eye on it! When it starts boiling, reduce the heat just enough to ensure it maintains that full boil. Let it simmer away for about 9 minutes, adjusting the heat as necessary to prevent burning. You’re aiming for a temperature of around 220°F (104°C), which is where the magic of setting begins!
Test for Doneness: Once you think it’s ready, drop a small spoonful of the preserves onto that cold plate from earlier. After a minute, gently push it with your finger. If it wrinkles and holds its shape, your preserves are ready to rock.
Add Flavor: When the jam is done, it’s time to stir in the vanilla extract and give it a lovely mix to infuse that aromatic flavor throughout.
Cool it Down: Remove the saucepan from the heat and place it on a wire rack to cool completely. This process should take about an hour.
Store: Finally, transfer your fabulous preserves into clean jars. They’ll keep in the refrigerator for about a week, but any leftovers beyond that—if you can resist—is best frozen. They’ll stay good for up to a year in the freezer, making them a fantastic option for future breakfasts.

Storing & Reheating
To keep your rhubarb preserves fresh, store them in airtight jars. At room temperature, they last for about a week when opened. For longer storage, keep them in the fridge—using glass jars is ideal as it preserves quality. You can also freeze the preserves; just ensure you leave some room in the jars, as jam expands when frozen. They can be reheated on low in a saucepan, stirring gently, to revive their texture and flavor.
Chef’s Helpful Tips
- Avoid Burning: Keep the heat low towards the end of the cooking time to prevent the rhubarb from burning. Stir frequently!
- Flavor Tweaks: Want to enhance your preserves? Experiment with adding a pinch of cinnamon or a few slices of ginger during cooking.
- Texture Check: If your preserves seem too runny, cook a bit longer and retest on the chilled plate.
- Make-ahead: These preserves can be made ahead of time. They taste even better after a day or two in the fridge as the flavors meld.
If you’ve never tried making your own preserves, this recipe is a gentle introduction. With simple ingredients and straightforward steps, you’ll soon be enjoying homemade rhubarb preserves that are far superior to store-bought versions. They make everything—from pancakes to yogurt—extra special. I encourage you to experiment with flavors and share this delightful treat with family and friends.
