Having the good fortune to have cooked with the Triggs and cooked beside them in a bunch of major comps,they will tell you to learn to cook the product, until it suits you -on your cooker.
Smokin' says that all the time.
One brand of ribs John likes was purchased by Smithfield-as many brands have been.
If you are west of the Miss River,you can buy the spares at Publix.East of the River,we get those cut to the Smithfield manufacture.
Like many comp cooks, the Triggs buy IBP from Sam's.
Remember,John and Trish have cooked as many as 48 weekends a year,so you have to know where the meats can be found, consistently.Many of your condiments must be found consistently on the road.
Like many comp cooks,they buy three slabs to get two.The heavy ribs with some fat cook juicy,but require a good bit of trimming to look like what you see on TV.
That group of ribs produces the six they turn in,that the camera shows.
Just a couple of thoughts.
