Came across this channel recently. Chris Young is the creator of the Joule Sous Vide stick as well as the Combustion thermometer line. He’s going some really interesting, science-based, cooking videos. This one in particular, don’t let the title fool you. He goes more in depth on WHY steaks are juicy.
Could be the sort of clickbaity style of the title combined with no actual summary. A lot of people will have heard a bunch of claims like these, some of which aren’t even fake.
