Due to the shameful state of commercially packaged ‘Mexican’ chorizo in the U.S., I usually make my own. I never include pork salivary glands or lymph nodes!
The chile mix depends on what you have available. The listed varieties are easy to get at Mexican markets or online from Penzeys. I include a lot of paprika for color, enough de arbol for heat, and the rest for the main flavor. The vinegar will partially mute the chile heat; after a few hours cook a little to check for balance.
