The foundation of this salsa lies in how you prepare the ingredients. Begin by heating a comal, a large non-stick skillet, or cast iron over medium-high heat. If using a standard oven or air fryer, refer to your specific appliance instructions, but the goal remains the same: charred, soft vegetables.
Place unwrapped onions, garlic cloves, and fresh chiles directly on the hot surface. Wrap the tomatoes in aluminum foil before placing them on the comal to keep their skins intact while they soften. Turn everything regularly to ensure even cooking. You are looking for a soft texture throughout and visible charring on the outside, which adds that essential smoky note.
