this guy managed to cook like shit and proliferate a blow torch myth (while cooking in his hiking socks)
he has a 100 dollar vacuum sealer, 50 dollar irt, 30 bucks of steak, and hold on bro i gotta boil some more water in my tea kettle to cook my steak in an igloo
the water is also not being circulated and only heated to 130 so you are essentially cooking in an incubator for bacteria and food borne illness congrats!
it's not a 7th grade science experiment, it's dinner
if you don't want to purchase a searzall just sear in pan; an unfitted torch will ruin any maillard reaction with overwhelming 'torch taste'
