As a competitor and BY cook, I'm 100% in support of commercial rubs all the way. Saves me time and they are damn good. That whole 'Quality Control' thing really does work IMO. These commercial rub artists....that sounds farking dirty..... anyways, they have it dialed in.
Additionally, I'm not saving $ by making my own rubs.....far from it actually. We used to make our own rubs, but it just wasn't good enough....and I was sick and tired of having to buy a new jar of Turmeric/Coriander/Goat Nut Powder/YouNameIt to keep fresh ingredients in our rubs.
We've been using the same basic 4 rubs for the past 5 years with much success, both in the BY and at comps.
In no particular order:
I totally respect the guys that make their own rubs and are happy with them. This homeboy doesn't have time.
