Step 1 In a mortar or small bowl, mash the garlic in the salt until dissolved to a paste. Place in a serving bowl. Add the onion, tomatoes, chiles (salsa should be hot, but adjust amount of chiles to level of heat desired) and stir to blend well.
Step 2 Stir in the lime juice and cilantro. Let stand at room temperature about 2 hours for flavors to blend. Serve at room temperature as an accompaniment to cocido.
