Chorizo ibérico — made from Ibérico pig with smoked paprika and garlic — is a different beast from ordinary chorizo. The fat is richer, the flavor deeper, the color more intense. Sliced thin at room temperature, it needs nothing.
Source ibérico-grade chorizo from a reputable Spanish producer. Serve at room temperature, sliced 3mm thick. Excellent alongside jamón on a board or as an independent course with good bread and red wine.
