Wow, I don't know how to choose, because so much of what I smoke/cook depends on my mood. Tri tips, brisket, pork butts, spare ribs, every kind of poultry (whole, parted, boneless/skinless), jerky, buckboard and back bacon, I love doing it all.
Probably the meat I most look forward to buying and smoking/grilling every year is prime rib cut into cowboy steaks. I've only got one left in the freezer, but the holidays will be here soon enough to stock up again.
Oh, and anything Italian. I made Pasta Carbonara last night. Such delicious, bacony carbs. There are two servings left. My wife made it clear this morning I'd be packing my bags if I eat her portion for lunch. I'm weighing my options.
