When you can explain the science to me, I'll believe you.
I'm not that kind of cook. That's why I put the [snicker] comment in there. I'm sure there is something to the science of cooking, but I rely more on my taste buds. Call me old fashioned. The episode I'm referring to if you're interested had to do with smoking chicken. I did a search but could not find the one I saw on TV as there are 15 seasons of ATK and half must be about cooking chicken.
But the BBQ smoke must be treated as an ingredient. Too much smoke or too little smoke and your product is affected. Or the wrong kind of smoke. Even the temperature of the smoke. This all plays a role in desirable taste.
It's not even really up for debate. There is not an electric smoker on the market that can create the same flavor as a stick burner. I'm talking a desirable flavor. From Texas to Memphis to North Carolina to Kansas City you can't name one referable BBQ establishment that cooks on an electric smoker.
It's not just for nostalgia or tradition that great BBQ establishments cook over wood heat, either. It's the flavor. Whether you're cooking low-and-slow or hot-and-fast, it's the flavor that comes from a proper burning wood fire that cannot be replicated.
