I came across a similar recipe last year, and have adjusted it some. I never measure anything, but I'll guess on the measurements.
I marinade overnight in 1/2 cup Worcestershire sauce, either teaspoon of garlic powder or a clove of fresh garlic, and about a tablespoon of tabasco sauce. Optional: when ready to cook, I take them out and trim the fat, but I prefer lean meat. I fire up the grill on a medium-high heat, and mix up a rub. For the rub, I use about 3/4 cup brown sugar, 1 1/2 tablespoons ground coffee, and I may add a bit of rosemary. This would be where to add any seasonings you prefer. I mix it all up with about a 1/4 cup of olive oil to help it stick. Before I put them on the grill, I brush it on. I grill about 5-10 minutes per side depending on the duck. I just did goose today, and it was more like 15 minutes to get a nice medium rare. The coffee gives it a nice smokey taste, I've had nothing but bad luck with the "liquid smoke". I've never found a better way to cook duck, even better than the old bacon wrapped and baked. Enjoy. :beer:
