1 (12 ounce) bag of cranberries
½ cup brown sugar
2 pears, chopped
2 teaspoons lemon zest
¼ cup minced ginger
½ teaspoon hot red pepper flakes
½ onion, chopped
¼ cup apple cider vinegar

Combine all ingredients in a medium-sized saucepan and bring to a boil. Reduce heat and simmer, stirring occasionally for about ½ hour. Berries should have burst by then. Cool and store in refrigerator. Serve at room temperature.
