1 tablespoon whole cloves
9 inches cinnamon sticks

Combine the vegetables, sugar, salt and cayenne in a heavy pot; place over low heat and stir until sugar is dissolved. Cook slowly, stirring occasionally , about 2 hours or until mixture thickens.
Add whole spices tied in a square of cheese cloth (don't use the powdered versions, they make the chili sauce look muddy), and the vinegar.
Cook until very thick.
