Anticuchos (Peruvian Beef Kebabs)

These spicy beef kebabs are served day and night in Peruvian restaurants and on street vendors ' carts. If you live in an area with a large Peruvian population, you can buy whole or ground amarillo aji. If not, use hot paprika instead, as we did when testing the recipe. We also tried Spanish smoked paprika, which you can find at www.tienda.com .
To prepare the beef, combine the first 7 ingredients in a large bowl; mix well. Cover and refrigerate for 3 hours.To make the fire roll, combine 1 teaspoon paprika, 1 teaspoon salt, 1/2 teaspoon pepper, turmeric, and parsley.Prepare the grill.Remove the beef from the bowl, rinsing off the marinade. Line beef on each of 6 (10-inch) skewers. Beef grate on a coarse grater. Place the kebabs on a grill rack greased with cooking spray; cook for 6 minutes or until desired browning, turning once. Serve with baked yellow pepper sauce.
