Homemade Rhubarb Ginger Jam

Making homemade jam can feel like a daunting task, especially when you’re juggling work, family, and everything else life throws your way. Most of us assume it requires special equipment, hours of cooking, or some kind of secret grandma-approved technique passed down through generations.

That’s why this rhubarb ginger jam recipe has become my go-to favorite: it’s straightforward to make, needs just a handful of ingredients, and brings a perfect balance of tart and sweet that store-bought versions just can’t match.

What Kind of Rhubarb Should I Use?

For jam-making, you’ll want to look for fresh, bright pink rhubarb stalks that are firm and crisp – avoid any that are limp or have brown spots. While both hothouse (forced) and field-grown rhubarb will work in this recipe, forced rhubarb tends to be more tender and has a prettier pink color that looks beautiful in jams. The stalks should be about thumb-width – if they’re much thicker, they might be woody and tough. When prepping your rhubarb, remember to remove all the leaves since they’re not edible, and give the stalks a good wash before chopping them into pieces.

Options for Substitutions

While making this jam, you have some flexibility with the ingredients. Here’s what you can switch up:

• Rhubarb: Fresh rhubarb is the star here and can’t be substituted – it’s what makes this jam unique! However, you can use green rhubarb instead of pink, though the final color won’t be as rosy.
• Sugar with pectin: If you only have regular sugar, that works too! Just add 1 packet of powdered pectin or 2-3 tablespoons of liquid pectin to help the jam set properly. You could also use a sugar substitute designed for jam-making, but check the package for the right amounts.
• Lemon: No fresh lemon? Use 2 tablespoons of bottled lemon juice instead. The zest can be skipped if needed, though it adds nice flavor. You could also use lime as a replacement.
• Crystallized/stem ginger: If you can’t find crystallized ginger, you can skip it or add an extra tablespoon of fresh ginger. Some folks like to use candied orange peel as an alternative for a different but equally good flavor.
• Fresh ginger: Ground ginger works in a pinch – use 2-3 teaspoons instead of the fresh piece. You can also use ginger paste from a tube, about 2 tablespoons should do it.

Watch Out for These Mistakes While Cooking

The biggest challenge when making rhubarb jam is getting the texture right – cooking it too long will break down the rhubarb pieces completely, while not cooking it enough will result in a runny consistency that won’t set properly.

A common mistake is skipping the maceration step – letting the chopped rhubarb sit with sugar for at least 2 hours (or overnight) helps draw out excess moisture and ensures a better set for your jam.

Temperature control is crucial – a rapid boil can cause the jam to burn on the bottom, so maintain a gentle rolling boil and stir frequently to prevent sticking, while using a thermometer to reach the setting point of 220°F (104°C).

For the freshest ginger flavor, add the fresh ginger at the beginning of cooking but save the crystallized ginger for the last 5 minutes of cooking time, and don’t forget to test the set by placing a small amount on a cold plate – it should wrinkle when pushed with your finger.

What to Serve With Rhubarb Ginger Jam?

This sweet and zingy jam is perfect spread on warm, buttered scones or English muffins for breakfast or afternoon tea. You can also spoon it over plain yogurt or vanilla ice cream for a quick and tasty dessert – the ginger adds such a nice kick! If you’re feeling creative, try using it as a filling between layers of vanilla cake, or spread it on toast with a little cream cheese for a perfect balance of sweet and tangy. For a really simple snack, just grab your favorite crackers or a fresh croissant and add a generous dollop of this jam.

Storage Instructions

Preserve: Pour your rhubarb ginger jam into clean, sterilized jars while it’s still hot, leaving about 1/4 inch headspace. Once sealed properly with sterilized lids, unopened jars will keep in a cool, dark place for up to 12 months. The perfect way to enjoy rhubarb season all year round!

Keep Fresh: After opening a jar, keep it in the fridge and use within 4-6 weeks. The ginger helps preserve the jam naturally, but refrigeration ensures the best flavor and prevents any unwanted mold growth.

Gift: This jam makes wonderful gifts! Just add a cute label with the date it was made and storage instructions. I like to include a note suggesting it should be refrigerated after opening and used within 6 weeks for the best taste.

Ingredients

• zest and juice of 1 lemon
• 2.2 lb rhubarb
• 4 cm ginger (freshly grated for best flavor)
• 50 g crystallized ginger (finely chopped)
• 2.2 lb sugar with pectin

Step 1: Prepare the Rhubarb Mixture

Begin by washing the rhubarb under cold running water, then slice it into 2cm pieces.

Place the rhubarb pieces into a large ceramic or plastic bowl.

Add the jam sugar, lemon zest and juice, and chopped stem ginger.

Finely grate the peeled ginger directly over the rhubarb to infuse extra flavor.

Stir the mixture thoroughly, cover loosely with cling film, and set it aside for about 2 hours.

This resting period will allow the sugar to dissolve in the rhubarb juices.

Stir the mixture occasionally to speed up the process.

Step 2: Prepare for Cooking

While the mixture is resting, place a few saucers in the freezer so they are ready for testing the jam’s set later.

Once the rhubarb mixture is ready, scoop the fruit and all the sugary juices into a preserving pan.

Step 3: Cook the Conserve

Set the preserving pan over medium heat and stir until the sugar has completely dissolved.

Bring the mixture to a boil, then continue to cook at a fairly swift pace until the rhubarb becomes really tender and the conserve reaches its setting point.

This should take about 10-15 minutes.

Step 4: Test for Setting Point

To determine if the conserve has reached the setting point, drop ½ teaspoon of the jam onto a cold saucer from the freezer.

Leave it for 30 seconds, then gently push it with the tip of your finger.

If the jam wrinkles, the setting point has been reached.

If not, continue cooking the mixture for another couple of minutes and test again.

Step 5: Jar the Conserve

Once the setting point is achieved, remove the pan from the heat and let it sit for 2-3 minutes to settle.

Carefully pour the conserve into sterilized jars, ensuring no air bubbles are trapped.

Seal the jars immediately and allow them to cool completely before labeling with the date.

Your rhubarb ginger conserve is now ready to enjoy!
