Preserving fruit is surprisingly easy and very satisfying—even more so when it's a fruit you really love or a fruit that you grew. One of the best ways to make your kumquats last you throughout the year is to turn them into jam so you can enjoy them anytime in yogurt or on toast.
The sweet and tart contrast of kumquats makes them perfect for creating a delicious jam. Add a cinnamon stick in the pot for a hint of spice with your citrus if you love the spice and citrus combo.
This easy recipe only requires just a few ingredients, some jars, and a little bit of time.

- 2 cups sliced kumquats with seeds removed
- 1 cup water
- ½ cup sugar
- ½ cup packed brown sugar
- 1 tablespoon lemon juice
- 1 cinnamon stick (optional)
- Cutting board
- Mixing bowl
- Measuring cups
- Measuring spoons
- Immersion blender
- Glass jar
Prepare the kumquats:
- Slice the kumquats and remove any seeds and add them to a mixing bowl.
- On top of the kumquats add the water, sugars, lemon juice and cinnamon stick if you’re using it.
- Stir together and let the kumquats sit for an hour to macerate, which will help pull the fruit’s natural sugars out.
Make the jam:
- Add the prepped kumquats to a pot and bring to a boil on medium-high heat.
- Reduce the heat to low-medium and continue to stir occasionally as the mixture simmers for 30-35 minutes or the mixture reduces by half and thickens into a syrup-like consistency.
- If using a cinnamon stick, take it out after the first 10 minutes of cooking.
- To know you’ve cooked the jam long enough, put a few plates in the freezer. When you’re ready to test your jam, drop a bit of the jam on the plate to see if it gels up. If it runs everywhere, it’s not done but if it thickens and gels, the jam is cooked through. You can also use a thermometer and once the temperature reaches 220 degrees Fahrenheit, the jam is done cooking.
- Once the jam is done cooking, use an immersion blender to blend everything up before transferring to a glass jar.
- The jam will thicken up in the glass jars as it cools.
Top your jars with a few fresh kumquat slices and give them away as gifts. We all need gifts to have one hand and jam makes an easy one to store and give away for later!
Use your jam in oatmeal, toast, buttery croissants, yogurt parfaits - the options are endless!
