You can drain the chorizo grease for this dip if you would like, or not. I have used 2 different types of chorizo for this recipe. This one from my local Walmart and this one from Porter Road. The Cacique brand definitely had more grease and I could have drained it, but I didn't. It was fine not to, but also would have made mixing at the end a little easier since there was a bit more fat/liquid to stir in. The Porter Road chorizo gave off little to no grease, so it was not even necessary to drain. Totally is just a personal preference.
