18. Chef José Andrés says that comparing pimentón, a Spanish smoked paprika, to the supermarket variety is like "comparing it to red powder." Pimentón is the sweetly smoky flavor in everything from chorizo sausage to paella. Look for dulce (sweet) and de la Vera on the label. Peppers from the La Vera region are always smoke-dried; in other regions they are sun-dried.
