Rhubarb and ginger jam has a lovely balance that keeps every spoonful interesting. The rhubarb brings a fruity tartness, the fresh ginger adds warmth, and the crystallised ginger gives little bursts of sweetness and texture throughout the jar. If you enjoy preserves that feel lively rather than overly sweet, this is a recipe worth keeping close each spring.
This rhubarb and ginger jam is also pleasingly direct to make. You do not need a long ingredient list, but each ingredient earns its place. Preserving sugar helps the jam set, lemon juice sharpens the flavor, and the mix of fresh and crystallised ginger gives the finished jam real character. It tastes wonderful on toast, but it is just as useful in baking, spooned over yogurt, or tucked into simple desserts.
Rhubarb and Ginger Jam
A good rhubarb and ginger jam should have a set that spreads easily rather than turning stiff or sticky. This recipe gets there by boiling the fruit mixture until it reaches setting point, then stirring in the crystallised ginger at the end so those little pieces stay clear and distinct.
Another thing I like about this jam is that the lemon and ginger stop the rhubarb from feeling flat. Rhubarb has a gentle fruitiness, but it often needs a little support. Here, the lemon adds brightness and the ginger adds warmth, which gives the preserve a fuller flavor.
Because the batch makes about four medium jars, it is a practical size for home cooks. It is enough to keep one or two jars for yourself and still have some to share or store away.
Ingredients
For this rhubarb and ginger jam, you will need:
- rhubarb, washed and sliced into 2 to 3 cm pieces
- jam or preserving sugar
- water
- fresh ginger
- juice of one large lemon
- crystallised ginger
- optional ginger syrup, or stem ginger with syrup
The rhubarb pieces do not need to be tiny. A modest chop is enough because the fruit softens quickly once it reaches a boil. Fresh ginger gives the jam its warm base flavor, while the crystallised ginger adds another layer that is sweeter and slightly chewy.
The optional syrup is a nice extra if you have it. It adds another gentle ginger note without changing the feel of the jam too much. Still, the recipe works well without it, so there is no need to worry if you only have fresh and crystallised ginger on hand.
How to Make Rhubarb and Ginger Jam

The first job is preparing the jars. Sterilising them before you begin means you can fill them as soon as the jam is ready. The recipe gives a simple method: soak and scrub the jars in very hot water, then dry them in a low oven. The lids are treated with freshly boiled water and dried separately.
It is also smart to place a saucer or small dish in the freezer before you start cooking. That cold plate is what you will use to test the setting point later. It is a simple step, but it makes a big difference when you want to know whether the jam is ready for the jars.
Add the rhubarb, preserving sugar, water, fresh ginger, and lemon juice to a large heavy-based saucepan or preserving pan. Bring everything to a rolling boil, stirring so the mixture does not catch on the bottom. After about 15 minutes, start checking for the setting point.
To test it, place a small amount of jam on the chilled plate and leave it for about 30 seconds. Push it gently with a finger. If it wrinkles, the jam is ready. If it still looks loose, return the pan to the heat and try again a few minutes later.
When the jam has reached setting point, stir in the chopped crystallised ginger and the optional syrup if you are using it. Then spoon the rhubarb and ginger jam into the prepared jars and seal them tightly.
Ideas for Using Rhubarb and Ginger Jam
Rhubarb and ginger jam is lovely on toast, crumpets, or warm scones, but it can do much more than breakfast duty. Try a spoonful stirred into plain yogurt, layered into a simple sponge cake, or added to porridge when you want something bright and fruity.
It also works well in desserts where you want a little sharpness to cut through rich ingredients. A thin layer in a tart, a dollop beside cheesecake, or a spoonful folded into whipped cream all work very well. Because the ginger has a warm note, this jam feels at home in cozy bakes as well as lighter spring treats. It is especially handy when tucked into a bake like fruit-forward cupcakes or served alongside a chilled slice of creamy cheesecake.
Sterilising Jars for Jam
Sterilising jars is a practical part of jam making, not a fussy extra. Clean jars help your preserve keep well and taste fresh for longer. The method given in this recipe is simple and easy to follow at home: wash, rinse, dry in a low oven, and treat the lids with boiled water. For extra preserving guidance, the National Center for Home Food Preservation is a useful outside reference.
Have the jars ready before the jam reaches setting point. Once the rhubarb and ginger jam is ready, you want to work while it is still hot. That makes filling and sealing much smoother.
How Many Jars This Rhubarb and Ginger Jam Makes
This batch makes about four medium-sized jars, and the recipe card gives the yield as four 350 ml jars. That is a very comfortable amount for home jam making. It is large enough to feel worthwhile, but small enough to fit into an ordinary kitchen routine.
If you like to give homemade food as gifts, rhubarb and ginger jam is a nice choice. The flavor feels thoughtful and a little different from standard strawberry or raspberry jam, but it is still familiar enough to please most people.
More Recipes Using Rhubarb
If this rhubarb and ginger jam has made you want to cook more with rhubarb, there are plenty of directions to go next. Rhubarb works beautifully in cakes, tarts, fritters, and pie fillings because its tartness gives balance to sweeter ingredients.
One of the nicest things about rhubarb is how flexible it is. It can be rustic and simple or dressed up for a special dessert. Once you have a few stalks in the kitchen, there is usually more than one good way to use them. A spoonful of this jam also sits nicely beside homemade pie filling ideas and other sweet bakes from the dessert collection.
Storage Notes
The recipe notes say that properly sterilised, unopened jars can keep for up to a year in a cool, dark cupboard. Once opened, the jam should be kept in the fridge and used within about three weeks. That makes it a very practical preserve to make when rhubarb is in season and you want to hold onto that flavor a little longer.
