Just as an aside, chorizo's well better than salami.Controversial! The rows we've had between Italian and Spanish colleagues...although nothing compares to the olive oil wars.
As with everything it depends on context. Melt in your mouth salami as part of an antipasti in a restaurant in Naples is heaven. Plastic salami from a plastic packet in ASDA, then give me chorizo every time.
As a cooking ingredient, chorizo walks it over salami, no contest.
