• Slice partially frozen pork into very thin slices, going against the grain, if possible. Next, slice one large onion into rings. Set the pork and onion aside while you work on the marinade.

Marinade

• Whisk marinade ingredients into a measuring cup.
• Layer the marinade, onion, and pork into a glass dish or plastic bag.
• Massage the marinade into the pork and allow the pork to marinate for 2 or more hours in the refrigerator.

Chipotle Crema

• Meanwhile, add the chipotle crema ingredients to a blender or food processor. Pulse until smooth.
• Add the sauce to a squeeze bottle using a funnel.

How to Cook the Tacos Arabes

• Once the Tacos Arabes meat is marinated, cook the meat in batches in a hot cast-iron pan until it is cooked through and has crispy edges. This should take approximately 3 minutes per batch.
• If you are lucky enough to own a rotating spit on your grill, you can stack the meat on the spit and cook it on the grill until charred on the outside and cooked all the way through.
• Yet another option is to stack the marinated meat onto a few skewers that are anchored on the top and bottom with one large onion, sliced in half. 
• Stand the spit on a foil-lined pan and bake in the oven at 350-degrees F for 45 minutes, broiling for a few minutes at the end.

How to Serve Tacos Arabes

• Slice the cooked pork into thin strips. Serve Tacos Arabes with pita bread or flatbread, accompanied by Marinated Sumac Onions, or diced onion, salad, and some chipotle crema on the side.
