This is such a simple recipe, and the results are amazing. Even if you disdain fresh kumquats, this concoction is worth a try.
1 pound of kumquats or so, cut in half and seeds flicked out.
1 cup water
2 cups sugar
1 teaspoon of a mixture of cinnamon, nutmeg and cloves
In saucepan, bring water and sugar to a boil. Boil for 3 or 4 minutes, which will thicken the sugar mixture to a syrup. Add fruit and spices. Lower heat and simmer for 10 minutes. Use slotted spoon to remove kumquats from the mixture. Continue to cook the syrup to about half what you started with, then pour over fruit, jar and refrigerate.
