This recipe is for a bone-in pork shoulder, or pernil. It is marinated in a garlicky paste for 1 to 3 days; the longer the better. Unlike other recipes in the database, it is cooked at a relatively high heat so that the result is a tender roast with crispy crackling or chicharons. Adapted from Daisy Martinez. Cooking time is approximate. The original recipe called for a 4.5 lb pork shoulder. The smallest I found was 8.5 lbs.
