In a medium saucepan over medium-high heat, bring sugar, water, orange zest, orange juice, and a pinch of salt to boil. Stir occasionally to dissolve the sugar.
Stir in cranberries. Simmer until slightly thickened and the berries begin to pop, about 10 minutes. Remove from heat and cool to room temperature.
Store covered in the refrigerator for up to 4 days. Or, pack in a freezer-safe container leaving 1 inch for expansion. Label, date, and freeze up to 3 months. Thaw overnight in the refrigerator.
Notes
Orange zest and juice:Zest the orange first, then cut in half to juice.
Cranberries: To use frozen cranberries, add them cranberries straight to the saucepan (no thawing needed) and add 2 minutes to the simmering time.
Yield: This recipe makes 2 cups cranberry sauce. It's enough for 8 servings, 1/4 cup each.
