Shhhh! Don't tell but I bought one of those monster pork shoulders at Costco. I made fair carnitas with half of it but what to do with the rest? I ground it up using my Kitchen Aid Food Grinder attachment(obviously any meat grinder will do, but the KA is handy) and added a bottle of Gay Caballero Very Hot Sauce and about 1/2 a cup of apple cider vinegar. After mixing it all up, I let it rest for 2 days and then I had some great chorizo. Chorizo and eggs with Rancho Gordo tortilla chips for breakfast.
