To explain what I mean, I think you can level up a cooking style. For example, pasta. At level 1, you’re boiling dried pasta and adding sauce out of a jar. At level 1, you add your own spices. Level 3, switch to fresh pasta. Level 4, make your own sauce. And finally at level 5, make the pasta from scratch.
So with BBQ, I guess level 1 would be cooking the meat so it’s neither burnt nor underdone. Maybe level 2 is mixing different meats/cuts that have different heat/time requirements and cooking well. Further levels = ?
maybe level 1 is on a grill with gas. another level is a smoker, or wood. another is making your own bbq sauce. another is stuffing a chili pepper with cheese and wrapping it in bacon and painting that with maple syrup.
