Make variations of this refreshing orange-lemon syrup by stirring in an 8-ounce can of drained pineapple tidbits or an 11-ounce can of drained mandarin orange sections. Serve this syrup over pancakes, fresh fruit, or grilled chicken.
In a medium saucepan combine the orange peel or lemon peel, orange juice, lemon juice, and sugar. Bring to boiling over medium-high heat, stirring occasionally. Reduce heat and simmer, uncovered, about 15 minutes or until reduced to 3/4 cup, stirring occasionally. Serve warm or cool. Cover and refrigerate remaining syrup for up to 1 week. Makes 3/4 cup.
