Thank the Ottoman Empire for the taco al pastor (via PRI)

At the Supermercado Mexico in Portland, Oregon, you’ll find a turning spit of pork, basted with chili and onions, dripping fat and flavor. Shave some off into a tortilla and you’ve got a taco al pastor, the classic Mexican street food.

It’s a similar scene halfway across the world in Jerusalem. At the hole-in-the-wall Al Waary restaurant, there’s a vertical rotisserie of beef spinning next to the flames, flavored by tangy vinegar. Shave some off into a pita, and you’ve got shawarma — the quintessential Middle Eastern street meat.

If you’re thinking these beloved dishes might be linked, you’re right. So we hit the street food trail to find out, starting in Jerusalem.
