Slices of candied kumquats add zest to our Orange and Buttermilk Parfait.
Bring sugar and 1 cup water to a boil in a small saucepan over medium-high heat, stirring until sugar has dissolved. Reduce heat to medium-low. Add kumquat slices; simmer until tender and almost translucent, about 15 minutes. Let cool in syrup. Kumquats can be refrigerated in an airtight container up to 2 weeks.
