yeah...that was probably the most disgusting.
there have been things Irvine says on the show that seem questionable, such as:
-cooking raw meat in a finished sauce. I know a lot of italian families that put raw sausage, meatballs and chicken into sauce to poach it and infuse flavor into the sauce. I think as long as everything is cooked thoroughly, you are good. (not to mention that you see people poach raw meat in sauce regularly in Diners, Drive ins and Douchebags)
-he criticized a guy for using a store bought spice mix (seasoned salt) as a meat rub, then promptly shows him a recipe for a rub that included at least three store bought spice mixes in it (curry powder, seafood seasoning and one I can't recall off the top of my head).
-complaining of all the things catching dust, then his designers creating dusting nightmares in the place (open and glued down milk bottles, a motorcycle under a counter, hanging gigantic ceiling fixtures, crazy looking lamps and in one, a gigantic three dimensional plywood wall decoration).
