Fire pit grill

Boil in the bag followed by a flame thrower?

Or you could just marinade it in petrol then chuck a match on it.

Hmm, ever heard of Uber Eats and similar?

Every one to his own taste - but if you really think that sous vide is "boil in the bag" then I can understand the attraction of Uber Eats or even McD....
