Pili pili, often called piri piri, is served as a table condiment in West Africa, where it heats up grilled meat, poultry, shrimp, and fish. Nearly any green chile can be used to make this sauce. Some recipes call for tomatoes or tomato sauce to be added.
Popular with the Yemenite Jews in Israel and in the Middle East, this hot sauce starts with a paste of garlic and peppers plus whatever spices the individual cook chooses, along with cilantro and/or parsley. There are two versions, this green one and a red one that uses red sweet and hot peppers. Tomatoes are sometimes added to tone down the sauce, which can be quite spicy. This quick and easy sauce serves as a table condiment, as a sauce for grilled fish or meat or for eggs, or can be added to soups and stews just before serving. It goes especially well with lamb kabobs.
This traditional tapa is not anything like a Mexican tortilla. A Spanish tortilla is a large, thick, omelet-like cake made with potatoes and eggs and is served at room temperature. Romesco sauce is an all-purpose Spanish sauce that is served with a wide variety of dishes. From the Tarragona region, this Catalan sauce combines two of the most popular horticultural imports from the New World---chiles and tomatoes. The sauce gets its name from the romesco chiles that are used but are not readily available outside of Spain. The combination of ancho and New Mexican chiles approximates the taste.
