Preheat the oven to 325 degrees. In a medium saucepan, mix the brine ingredients, warm over a low heat and whisk thoroughly. Cut the stale tortillas into strips or wedges. (If the tortillas are fresh, dry them by spreading them on a baking sheet and letting them sit out, room temperature, for 1 hour or more.) Briefly dip the tortilla pieces into the brine, then shake off the excess water. (A longer soaking in the brine will make the tortillas take on a more pronounced flavor.) Spread the prepared tortilla chips in a single layer on a baking sheet. Bake, turning occasionally, until they are crisp and golden brown, about 12 to 15 minutes.
