Pour the vinegar into a medium saucepan and incorporate the toasted chiles and garlic, the sliced onions, bay leaves, salt and pepper. Set over medium-high heat, let it come to a rolling boil and then immediately turn off heat. Let cool. Can keep in the refrigerator for up to a couple weeks in an airtight container.
