WHY YOU WILL LOVE THIS EASY KUMQUAT JAM RECIPE

If you’ve never cooked with kumquats before, this is the best way to start. Their skins are thin and edible, which means the whole fruit can be used for a flavorful marmalade. Unlike orange marmalade, Kumquat Marmalade with Sugar has a unique balance of tart and sweet that brightens breakfast or adds a gourmet touch to baked goods. This easy kumquat jam recipe is small-batch friendly, requires only four ingredients, and yields just the right amount for sharing or keeping all to yourself.

INGREDIENTS FOR KUMQUAT MARMALADE WITH SUGAR

This preserve captures the unique tart-sweet balance of kumquats in a simple, small-batch recipe. It’s quick to make, perfect for beginner cooks, and creates a gourmet jam you’ll be proud to share.

• Kumquats – The star of the recipe, offering a tangy citrus flavor with edible skins that soften into tender slices when cooked.
• Lemon Juice – Adds brightness and a natural boost of pectin, which helps the marmalade set.
• Water – Creates the syrup base that gently softens the fruit and balances the flavors.
• Sugar – Preserves the kumquats, enhances their natural sweetness, and gives the marmalade its glossy finish.

HOW TO MAKE EASY KUMQUAT JAM RECIPE

This marmalade highlights the bright citrusy bite of kumquats in a straightforward, small-batch recipe that’s easy for beginners yet impressive enough to gift.

1. Prep the fruit – Wash the kumquats. Slice into rounds and remove seeds (optional). For a chunkier texture, cut them in halves.
2. Make the syrup base – In a saucepan, whisk together the lemon juice, water, and sugar. Cook over medium heat until the mixture turns clear. Stir steadily to avoid burning.
3. Combine with kumquats – Add the sliced kumquats to the hot syrup. Toss gently with a spoon or spatula to keep slices intact.
4. Cook the kumquats – Cover and cook for 6 minutes over medium-high heat. Remove the lid, gently press the kumquats under the syrup with a slotted ladle or spatula, then cover and cook another 6–10 minutes. Turn off the heat.
5. Rest and store – Let the marmalade rest in the pan for 10 minutes. Transfer to clean glass jars.

Yields about:  1½ to 2 pints of marmalade (24-30 oz / 3 to 3¾ cups / 720–900 ml)

Variations to Try:

• Add fresh ginger slices or a pinch of cardamom for a warming twist
• Stir in a splash of orange blossom water for floral notes
• For a festive touch, try a hint of vanilla or cinnamon

Serving Suggestions

Spread Kumquat Marmalade with Sugar on warm toast, biscuits, or scones for a cozy breakfast. Stir a spoonful into plain yogurt or oatmeal for a citrusy boost, or swirl it between cake layers as a fruity filling. It also makes a thoughtful homemade gift that shows off your kitchen skills and the beauty of seasonal produce.

Storage Tips

Store the marmalade in clean glass jars in the refrigerator for up to 3 weeks, or freeze for up to 3 months. For shelf-stable storage up to 1 year, process jars in a boiling water bath using trusted canning guidelines for your jar size and altitude. A standard water bath time for pint jars is typically 10 minutes. 

Sweet Little Jars to Try Next

If you’re in the mood to keep playing with sweet, special condiments, there are so many cozy directions to go next. I love tucking a spoonful of Glacéed Lemon Preserves alongside cheese boards, swirling silky lemon curd into yogurt or cake layers, or simmering a pot of slow-cooked apple butter when the kitchen needs to smell like comfort. In warmer months, apricot sauce and fresh cherry sauce are little jars of sunshine that feel just as at home on toast as they do spooned over dessert. Think of these as quiet, reliable recipes you’ll reach for again and again.

EQUIPMENT NEEDED

• Sharp knife for slicing kumquats evenly
• Cutting board
• Medium saucepan – this is the stainless/ceramic cookware set I prefer
• Heat-resistant spoon or rubber spatula
• Slotted ladle for pressing fruit under syrup
• Clean glass jars with lids (Weck Tulip Jar)

Calories 104kcal

Ingredients

• 1 ½ pounds kumquats sliced and de-seeded (680 g)
• 2 Juice of lemons (90 ml) about 6 tablespoon
• 1 cup water (240 ml)
• 2 cups granulated sugar (400 g)

Instructions

• Prep the fruit - Wash the kumquats, slice them into rounds, remove any seeds (optional). You need 1 ½ pound (680 g) sliced, deseeded kumquats. Kumquats can also be halved for a chunkier result.
• Make the syrup base - In a saucepan, whisk together the lemon juice, water, and sugar. Cook over medium heat until the mixture turns clear. Stir steadily so it does not burn.
• Combine with prepared kumquats - Place the sliced kumquats into the saucepan with the hot syrup. Use a spoon or spatula to toss gently so the slices stay intact and don’t break apart.
• Cook the kumquats - Cover the pan with a lid and cook for 3-5 minutes over medium-low heat. Remove the lid, then press the kumquats gently under the syrup with a slotted ladle or toss gently with a rubber spatula. The idea is to keep the slices whole. Continue to cook uncovered on a bubbly low heat for another 15-20 minutes. Turn off the heat.
• Rest and store - Let the kumquats rest in the pan for 5 minutes, then spoon into clean glass jars. Refrigerated, this marmalade will last up to 2 months (and often longer) while maintaining flavor and texture. You may also process in a water bath for long-term shelf stable storage.
