Then in a large bowl, combine the preserves, vinegar, grated fresh ginger, cayenne, and kosher salt, ore or less to taste.
Reserve 1/4 cup of the glaze mixture. Add the chicken drumsticks to the bowl and toss to coat.
Grill chicken, covered, turning occasionally. Cooked all the way through, 25 to 30 minutes, basting with reserved glaze mixture in the last 10 minutes of cooking.
