Salsa de Molcajete (Roasted Tomato and Green Chile Salsa)
This is archetypal salsa, made from tomatoes, green chiles, cilantro, and lime. But more than a mere mix of ingredients, salsa de molcajete uses centuries-old techniques to combine flavors, bringing out the best of each.
Roasting tomatoes gives them a sweet and complex taste; rinsing onion under cold water makes it crisp; and crushing roasted garlic and chiles in a mortar releases their full flavor. Though it's typically done in a molcajete (Mexican lava rock mortar), you can also make this salsa using a marble mortar and pestle (as we did). Finely chopping the garlic and chile in a food processor then adding the tomatoes and pulsing the mixture until everything is coarsely pureed will yield great-tasting results as well.
