Ingredients
1 ½poundskumquatssliced and de-seeded (680 g)
2Juice of lemons(90 ml) about 6 tablespoon
1cupwater(240 ml)
2cupsgranulated 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.
