Soak the chipotles in water until they rehydrate, at least one hour, then drain. In a saucepan, add ½ of the vinegar, ½ of the garlic and the brown sugar. Cook this mixture for about 20 minutes, then add the chipotles.
In another pan, combine the green chile, tomato, remaining garlic, peppercorns, bay leaves, cumin, remaining vinegar, and salt to taste. Cook for about 30 minutes, covered, over a medium heat. Add the chipotle chile mixture, stir well, and store in sterilized jars.
