Spain’s most famous sausage is also its least consistent: “chorizo” is a catchall term that encompasses virtually any sausage made from ground pork mixed with a generous dose of either sweet or spicy pimenton. Everything else — the coarseness of the grind; sausage length, width, density and curing time; any additional ingredients — can vary tremendously from region to region and kitchen to kitchen. The most popular version is a lean, dry, austere sausage made from pork, pimenton, and salt; it’s equally tasty sliced and paired with cheese, or chopped and fried in olive oil, served with bread for sopping up the spicy, flavorful drippings.
