Ingredients
- 4 cups chopped fresh rhubarb (about 1.5 to 2 pounds)
- 3 cups granulated sugar
- 1/4 cup water
- 1 tablespoon lemon juice (freshly squeezed is best)
Step-by-Step Instructions
- Wash and trim the rhubarb stalks, discarding any leaves or tough ends. Cut the rhubarb into 1/2-inch to 1-inch pieces.
- In a large, heavy-bottomed pot or Dutch oven, combine the chopped rhubarb, granulated sugar, and water.
- Stir well to coat the rhubarb with sugar. Let the mixture sit at room temperature for at least 30 minutes, or up to an hour, allowing the sugar to draw out the juices from the rhubarb.
- Place the pot over medium heat and bring the mixture to a gentle boil, stirring occasionally to prevent sticking.
- Reduce the heat to low and simmer, continuing to stir periodically to prevent scorching.
- Cook for 20-30 minutes, or until the rhubarb is tender and breaks down easily, and the jam thickens to your desired consistency. The jam should coat the back of a spoon.
- Stir in the lemon juice during the last 5 minutes of cooking.
- Carefully ladle the hot jam into sterilized jars, leaving about 1/4 inch of headspace.
- Wipe the jar rims clean, apply lids, and screw on bands until fingertip-tight.
- Process the jars in a boiling water canner for 10 minutes (adjusting for altitude if necessary). Alternatively, allow the jam to cool completely, then store in the refrigerator.
- Once processed, remove the jars from the canner and let them cool undisturbed on a towel-lined counter for 12-24 hours. Check seals; any unsealed jars should be refrigerated and consumed within 3 weeks.
Expert Tips / Pro Tips
For the best flavor, use fresh, young rhubarb stalks that are firm and vibrant in color. Avoid any stalks that appear withered or discolored. Stirring the jam frequently, especially as it thickens, is crucial to prevent scorching on the bottom of the pot. To test for doneness, you can use the plate test: place a small spoon of hot jam onto a chilled plate, let it cool for a minute, then push it with your finger. If it wrinkles, it’s ready. If you prefer a smoother jam, you can use an immersion blender for a few pulses directly in the pot, or mash the rhubarb with a potato masher during cooking. Sterilizing your jars properly is key for safe canning and long-term storage.
Variations & Substitutions
You can easily customize this classic rhubarb jam. For a delightful twist, add 1/2 teaspoon of ground ginger or cinnamon during the last 10 minutes of cooking for a spiced rhubarb jam. A small amount of mashed strawberries (about 1 cup) can be added along with the rhubarb for a classic strawberry-rhubarb combination. If you prefer less sugar, you can cautiously reduce the amount by about 1/2 cup, but be aware it may affect the jam’s setting consistency and preservation properties if canning. For extra zest, consider adding the finely grated zest of half a lemon to the mixture.
Serving Suggestions
This Classic Rhubarb Jam is incredibly versatile. It’s perfect slathered on your morning toast, crumpets, or English muffins. Swirl it into plain yogurt or oatmeal for a burst of fruity flavor. Use it as a filling for tarts, hand pies, or thumbprint cookies. It also makes an excellent topping for pancakes, waffles, or even ice cream. For a savory-sweet pairing, serve a dollop alongside pork or chicken dishes. Don’t forget that a spoonful stirred into hot tea or sparkling water can create a refreshing beverage.
Storage, Freezing & Reheating
Properly processed and sealed jars of rhubarb jam can be stored in a cool, dark place for up to 1 year. Once opened, or if not processed in a canner, the jam should be refrigerated and consumed within 3-4 weeks. Freezing is an excellent option for longer storage if you prefer not to can. Ladle cooled jam into freezer-safe containers, leaving headspace, and freeze for up to 6 months. To defrost, simply place containers in the refrigerator overnight. Reheating jam is generally not necessary as it’s typically served at room temperature or chilled, but if you wish to warm a small amount, do so gently in a microwave or small saucepan.

FAQ
Do I need to peel the rhubarb?
No, you do not need to peel the rhubarb for jam. The skin breaks down during cooking and contributes to the jam’s lovely pink color.
How do I know if my jam is set?
The easiest way to check for set is the “wrinkle test.” Place a small plate in the freezer for a few minutes. When your jam seems ready, spoon a teaspoon onto the cold plate. Wait 30 seconds, then push the jam with your finger. If it wrinkles, it’s set. If not, cook for a few more minutes and retest.
Can I reduce the amount of sugar?
You can slightly reduce the sugar, but be careful. Sugar not only adds sweetness but also acts as a preservative and helps with the jam’s gelling. Significantly reducing it might result in a looser jam and reduce its shelf life if canning.
Classic Rhubarb Jam Recipe
Ingredients
Method
- Wash and trim the rhubarb, then cut it into 1/2-inch pieces. You should have about 8 cups.
- In a large, non-reactive pot or Dutch oven, combine the chopped rhubarb, granulated sugar, fresh lemon juice, and lemon zest. Stir well to coat the rhubarb with sugar.
- Let the mixture sit at room temperature for at least 2-3 hours, or preferably overnight in the refrigerator. This draws out the juices from the rhubarb and helps dissolve the sugar.
- Bring the rhubarb mixture to a boil over medium-high heat, stirring occasionally. Once boiling, reduce the heat to medium-low and simmer, stirring frequently, until the jam thickens. This can take 30-45 minutes. If using, add the butter now to reduce foaming.
- To test for doneness, place a small spoonful of jam on a chilled plate and let it sit for a minute. Push the jam with your finger; if it wrinkles, it’s ready. Alternatively, use a candy thermometer; the jam is set when it reaches 220°F (104°C).
- Carefully ladle the hot jam into sterilized canning jars, leaving 1/4 inch headspace. Wipe the rims clean, place lids, and screw on bands until fingertip tight. Process in a boiling water canner for 10 minutes (adjusting for altitude if necessary).
- Remove jars from the canner and let them cool undisturbed on a towel-lined counter for 12-24 hours. Check seals; sealed jars can be stored in a cool, dark place for up to 1 year. Unsealed jars should be refrigerated and consumed within 3 weeks.
