The only time I had goat, I enjoyed it immensely. It tasted and felt much like venison.
As to what my favorite thing to cook on the grill is, well, if it's just my tastes that I'm talking about, it has to be either a good bone-in rib-eye steak, corn fed of course and at least USDA Choice quality, cooked over a solid bed of charcoal for 4 minutes per side, with just S & P.
Otherwise, it depends on who I'm trying to impress. I get equally good reviews with a pork crown-roast, and barbecued turkey. I love them both.
I haven't mastered ribs yet as my wife isn't crazy about them.
Other favorites are cut up chicken pieces over a solid charcoal bed, Cornish game hens over a divided charcoal bed, pork chops over a solid bed, planked walleye or herring, or pollok, or..., baked beans cooked over a solid bed with apple wood on the fire and the cover closed and the vents half closed (the smoke does wonderful things to baked beans
And then there are the grilled veggies. Wow, this is hard. I love so many things; shish kabobs, fruits, veggies, all kinds of meats, even breads.
Another favorite is a great grilled hamburger. When done properly, it's very juicy and has a great beef flavor. In fact, when done just right, it's similar in flavor to a good steak, only well-done.
And if you've never cooked a pizza on the covered kettle grill, then you just don't know what you are missing.
Interestingly, I don't care so much for hot-dogs cooked on the grill as they are usually overcooked. But give me a skewer and let me roast hot-dogs in the campfire, or over charcoal, and I'm a happy camper.
Now good sausage, with the skin on is a wonderful thing.
