Hmmm...I guess I don't fit your definition of bbq fun. Personally, I smoke / grill / cook / bake what I like to eat. It doesn't matter to me if it is different or not.
My wife likes to shake me out of my flavor zones on occasion because after almost 42 years of marriage she says things can start to taste the same to her. Consequently, I do recipe searches on the Internet, see what I have in the cabinet, and try new things. I change almost every recipe I try, either with ingredients or techniques. And the my recipes and techniques evolve with experience.
For example, I've been baking bread for a few years now. Two types are our favorites: rustic white bread and whole wheat sandwich bread. We go through a loaf of either bread in 3-7 days. I have both recipes perfected, but still fiddle with the technique.
Small differences can result in big changes. After making rustic breads last week, and whole wheat loaves yesterday, I decided to try a slightly different final proofing process with the rustic. I'll also try a lame (pronounced lahm-ay) cut on the whole wheat for the next round. I've posted recipes in the past that I've now changed. Those changes are probably the only hesitation I have about posting a recipe. It evolves with time.
With smoking, I prefer simple and hands off. I find the process exhausting when staying closely involved with a smoke for 6-16 hours. I'd much rather start the fire, let it settle, season the meat, toss it in the smoker (
WSM), and check its progress 4-10 hours later. I don't even use a meat probe until close to the end of a smoke, if at all.
So, no secrets with me. Ask and you shall receive...but it'll probably change it the next time I make it.
