Al pastor fish tacos basically translate to “shepherd style” fish tacos. This might seem a bit confusing, but stay with me.  “Al pastor,” when it comes to taco meat, refers to a particular way of marinating and cooking meat. The term came about in the 1900s when Lebanese merchants introduced their intensely delicious way of preparing lamb shawarma. Mexicans began referring to these Lebanese lamb cooks as “al pastor” or “shepherd” and used the term as they adopted their style of cooking and applied it to preparing pork.  Fish tacos al pastor uses the same bright, tangy, achiote-laced marinade that you see in more common pork-based Tacos Al Pastor Recipes. In addition to the spicy marinade, al pastor cooking also includes quickly searing the meat (or fish, in this case) to produce irresistible crispy and crunchy edges as well as the traditional pineapple salsa toppings.
