In a small mixing bowl, prepare spice mix by combining salt, white pepper, red pepper flakes, cinnamon, clove, coriander, ginger and nutmeg. In a large mixing bowl, combine ground beef, onion, parsley, mint and spice mix with your hands until thoroughly combined.
Form mixture into eight uniform logs. Skewer each log and hand-form tightly and evenly around the skewer, pulling the meat lengthwise from the skewer\'s tip toward handle. Leave about four inches of exposed skewer for a handle. Refrigerate at least 30 minutes or overnight covered in plastic wrap before grilling.
Grill skewers over medium-high heat until browned on all sides and cooked through (160° F internal temperature), about 2 minutes per side.
