Used both in cooking and as a condiment, these sauces come in a variety of styles. Sriracha (right) contains garlic and is made from chiles that are ground into a smooth paste. Chili-garlic sauce (left) also contains garlic and is similar to sriracha but the chiles are coarsely ground. Sambal oelek is made purely from ground chiles without the addition of garlic or other spices, thus adding heat but not additional flavor. Once opened, these sauces will keep for several months in the refrigerator.
