Mash minced garlic together with salt until it forms a paste. Place in a blender with the remaining liquid ingredients and spices.
Blend until all spices and ingredients are incorporated and the sauce is smooth.
Place a small amount of olive oil in a skillet and allow the pan to come to temperature over medium heat.
Place skirt steak in the pan without overcrowding the slices. Cook for 2-3 minutes on each side for very thin pieces, or about 4-5 minutes on each side for larger pieces.
Allow the steak to rest for about 10 minutes after cooking.
Serve with the garlic cilantro steak sauce drizzled over the steak.
Alternatively, you can thread the skirt steak onto skewers, broil them for about 3 minutes on each side, and use the sauce as a dipping sauce!
