In a medium saucepan, bring cranberries, granulated sugar, ½ cup water, celery, brown sugar, rosemary, salt, and red pepper to a boil over medium-high heat. Reduce heat to medium-low, and simmer until berries begin to burst and mixture begins to thicken, about 25 minutes. Remove from heat; stir in pecans and vinegar. Serve at room temperature or chilled (mixture will continue to thicken as it cools).
