Myth #3 (Bone-in steak has more flavor than boneless) seems a bit of a strawman, the version they disprove is "the bone somehow imparts flavour onto the meat", but they then go on to say that: > I personally find the tiny bits of connective tissue-rich meat, fat, and gristle stuck to the bone to be the tastiest part of the steak So yeah, unless you can get the bone out perfectly you'll get more flavoursome meat if yo…
> Also it's not entirely insane to believe bones impart flavour Brown stock is made from roasted bones, among other things, so I too feel somewhat skeptical about the claim that bones cannot import at least some sort of flavor.
It's not impossible that it would have an impact, but there's no obvious mechanism either. (And as the author points out, there's no particular reason why, even if flavour transfer was happening, it'd go the direction you want either.)
