Is this Mexican chorizo or Spanish chorizo?

My instinct (based on the other flavors in the dish) would have been to guess Spanish, but since the author mentions removing the casing and cooking the chorizo “until browned and cooked through,” I’m going to guess that this is a fresh sausage, which would indicate they used Mexican chorizo. Spanish chorizo is a hard, cured sausage. This is a great question, and hopefully the author will update the recipe.

Which ever your dinner table guests would enjoy more.
