This recipe for Polish kumquat-orange marmalade or kumqwat marmoladą (KOOM-kvaht marr-moh-LAH-dohn) has a splash of lemon juice to add brightness. Poles love their dżem (jam) and fruit spreads, especially rosehip marmalade in pączki. Try a dollop of this marmalade on Persimmon Quick Bread. It's awesome!

  • 1 pound kumquats (washed, stemmed, seeded, white pith removed. and coarsely chopped)
  • 1 medium orange (peeled, seeded, white pith removed, and coarsely chopped)
  • 2 cups sugar
  • 2 tablespoons lemon juice (1/2 a lemon)

Steps to Make It

  1. Place chopped kumquats and orange into a food processor and pulse until finely chopped. Measure fruit puree. You will need an equal amount of sugar. If you have 2 cups of fruit puree, you will need 2 cups sugar.

  2. Transfer to a heavy-bottomed saucepan with lemon juice. Bring to a boil, reduce heat and simmer until marmalade has thickened and coats the back of a spoon. The marmalade will continue to thicken as it cools.

  3. Sterilize as many jars and lids as you will need (probably 2-4 half-pint jars). Ladle hot marmalade into hot jars. Place lids on top and turn upside down on a clean towel. When jars are cool, turn upright and screw on caps. Store in the refrigerator up to 2 months or freeze up to 6 months. This also can be processed in a hot-water bath to keep at room temperature.
