I'd like to tag on and thank Max for the post.
The internet and forums are a wonderful thing in that they gives us 100s of bits and pieces of many folks techniques that we can't see,taste,smell,feel,etc.
Thanks to Smokin'Okie for giving us 101 s,so we can actually learn to cook the product correctly,before we start making all these adjustments.
Yes,as part of an overall technique,comp cooks try different things for specific reasons.
They often don't have a choice about adjustments[they have a 10 minute window to turn in the product-so they may have to trick it] and they could be serving a judge that eats one small bite to check texture,tenderness,mouthfeel.Taste could be to see if it is offensive.
They often discard the rest of the sample.
They often don't cook that way to actually eat themselves.
Randy mentioned above taking full COMPETITION courses from Mike Davis and John and Trish Trigg.
The Triggs were the mentor to Mike Davis and they no longer speak,just as a side note.
Another is that Trish Trigg is pretty close to the co-cook with John.If you know them,she will tell you she will not eat their comp ribs.Just a couple tidbits behind the "TV shows".
