Maple Beef Teriyaki - Ken Haedrich, Maple Syrup Cookbook

1/4 cup pure maple syrup
1/4 cup tamari or soy sauce
2 tablespoons vegetable oil
2 tablespoons sesame oil
1 tablespoon five-spice powder
2 pounds lean beef, sliced across the grain into 1/4 in strips

Mix the maple syrup, tamari, vegetable oil, sesame oil, and five spice powder together. Add the meat and toss well to coat it all. Cover and refrigerate overnight; stir occasionally. Drain the meat and pat dry with paper towels. Thread the meat onto skewers. (If using wooden skewers, soak them in water for 30 minutes before threading on the meat). Grill or broil the meat until tender, turning occasionally, about 6 minutes total for medium rare.
