grilled barbecued drumsticks

My daughter and her friend were excited all week long to make dinner last night.  They made grilled barbecued drumsticks, spicy baked potato wedges, corn and cookies.  It was a feast and everything was delicious.  They were mighty proud of these drumsticks and they had every right.  The homemade barbecue sauce was sassy and good.  Many fingers were licked at the kitchen table!

grilled barbecued drumsticks (cookbook:  Cooking Fun by Rae Grant)
1/2 cup ketchup
1 tablespoon molasses
1 tablespoon brown sugar
1 1/2 teaspoons Dijon-style  mustard (you can use spicy brown in a pinch)
1 1/2 teaspoon cider vinegar
1/4 teaspoon salt
6 large chicken drumsticks

(The original recipe told us to bake the drumsticks but we ignored that and prepared our grill instead of our oven.  If you want to bake your drumsticks, preheat to 375 with the rack in the middle of the oven and line a baking sheet with aluminum foil.)
Combine the ketchup, molasses, sugar, mustard, vinegar, and salt in a small saucepan.  Bring to a boil over medium-high heat.  Turn heat to low and simmer 5 minutes.
Put the drumsticks on the grill then use a pastry brush to spread the sauce evenly over the drumsticks.  Every 10 to 15 minutes, flip the drumsticks and brush with more sauce.  Grill for up to 55 minutes.  Serve hot.
