Colombian Chile Sauce

Ají belongs to an extended family of salsas and chile sauces served with grilled meats throughout South America (for another, see the the Peruvian ají amarillo sauce here). Even in Colombia, the recipe varies widely from pit master to pit master. Colombians use a variety of chiles. The best approximation in North America would be jalapeño or serrano peppers with a Scotch bonnet or two thrown in for aromatics and heat.
