In a saucepan over medium-high heat, bring the berries, vinegar, and water to a boil. Lower the heat and simmer for 5 minutes. Strain out the seeds and return the liquid to the saucepan. Add the brown sugar, cinnamon, cloves, ginger, salt, cayenne pepper, butter, and grated tangerine rind. Simmer until thickened, about 10 minutes. Let cool.
