Hi slowfoodgrrl. I've not seen candied kumquats around town, but have made them before for use in a cake. They're easy to do. The recipe I have calls for 5 cups of sugar and 2 pounds of kumquats and has both sliced and whole kumquats.
Cut three quarters of the kumquats into 4 slices each. Combine 5 cups sugar with 3 cups water in a large saucepan; bring to a boil. When the sugar has dissolved, add the sliced kumquats, return to a boil and allow to simmer for 8 to 10 minutes or until kumquats appear translucent. Remove from heat and allow the fruit to cool in the syrup for 30 minutes. Remove kumquats with a slotted spoon. Add the whole kumquats to the syrup, bring to a boil, and simmer for about 1/2 hour or until kumquats begin to collapse. Allow to cool in syrup for 30 minutes. Strain and reserve syrup.
I'd be interested to hear whether there are places that sell prepared versions of them.
