Soak 24 6-inch bamboo skewers in cold water 1 hour.
Cut beef into very thin 3-inch strips. Thread 1 or 2 strips on each prepared skewer and arrange in shallow dish.
In small bowl, combine soy sauce, honey, red pepper flakes, cumin, and turmeric.
Pour over beef, turning to coat. Let stand at room temperature 15 minutes.
Meanwhile, prepare grill or preheat broiler. Arrange skewers on grill or broiler rack 2-inches from heat source. (Make sure that bare ends of skewers are not directly over or under flame.) Grill or broil 30 to 40 seconds per side for medium-rare.
