If you can't find kumquats, don't panic — the recipe works fine without them.
Ingredients
2 (12-oz) bags cranberries, thawed if frozen
9 oz kumquats, trimmed and quartered lengthwise (1 1/2 cups)
1 cup water
1 1/4 cups sugar
2 tablespoons finely chopped peeled fresh ginger
2 whole star anise
1/4 teaspoon salt
Directions
Stir together all ingredients in a 4-quart heavy saucepan and simmer, uncovered, stirring occasionally, until berries have burst, 10 to 12 minutes. Remove star anise and cool completely.
