Iranian Shish Kebabs

Cut the beef filet into 1½-inch cubes, removing any excess fat or sinew as you work.

Combine the chopped onion, lime juice, allspice, salt, and black pepper in a bowl to create the marinade.

Add the beef cubes to the marinade and toss until all pieces are evenly coated; let rest for at least 15 minutes to allow flavors to penetrate the meat.

Preheat the grill or grill pan over high heat until it is very hot and lightly oiled.

Thread the marinated beef cubes onto metal skewers, spacing them slightly apart to allow for even cooking.

Place the skewers on the hot grill and cook for 3 to 4 minutes on the first side without moving them, allowing a light crust to form.

Turn the skewers and cook for another 3 to 4 minutes until the beef reaches medium-rare doneness with slight charring on the outside.

Transfer the kebabs to a serving platter and let rest for 2 minutes before serving; the meat will continue to cook slightly from residual heat.
