I was describing my method of BBQ in response to the gp. deep frying sous vide, liquid n or whatever other method is not bbq. Just like grilling is not BBQ. The style has a fairly specific meaning. If your ribs don't sweat three times in the process over six hours, you are doing it wrong.

Foiling them locks in the moisture. It absolutely doesn't eliminate it.

6 hours, low and slow. Or its not passable as BBQ
