Clean the kumquats by removing any leaves or sticks still attached.

Prick a couple of holes in the sides of each kumquat using a toothpick.

Put the kumquats in a small pot and cover with boiling water, enough to cover the kumquats. Bring the water to a boil over a medium heat and simmer for 10 minutes. Drain the water off the kumquats. Repeat this cooking method (adding boiling water and simmering for 10 minutes) two more times.

Drain the kumquats and keep aside.

Place the sugar in a pot and add 120 ml – ½ cup of boiling water.

Heat the pot for 10 minutes stirring occasionally (do not burn the sugar). Cook until the sugar mixture has thickened.

Add the kumquats to the thickened mixture.

Keep the mixture on a low heat for another 10-15 minutes or until the kumquats are translucent.

Squeeze the juice from half a lemon into the pot and stir until combined.

Leave the mixture on low heat for another minute or two.

Turn the heat off and leave the mixture to cool.
