Kumquats, about 1 cup, sliced into circles, simmered with 1/2 cup of water and 1/2 cup of sugar. A sprinkle of red pepper flakes, a big pinch of sea salt and a couple tablespoons of apple cider vinegar added when the mixture thickens. A few more minutes of simmering.
Use as a spread on bread or a topping to grilled meats.
