Your marinade is mostly a surface treatment, and that's fine

July grilling season myth-bust: marinade doesn't soak deep into meat no matter how long you leave it. According to the testing Kenji Lopez-Alt has published, most flavour compounds penetrate a few millimetres at best, even overnight. The big exception is salt, which does travel inward and genuinely seasons the interior. So the play is: salt early (even a day ahead), treat the marinade as a delicious coating, and save a spoonful of fresh marinade that never touched raw meat to brush on after cooking. That last one does more for flavour than six extra hours in the bag ever will.

Can confirm from far too many side-by-side tests. The reserved-marinade brush at the end is the single highest return move in grilling and nobody does it.

Finally. Every 'marinate 24 hours minimum' recipe is just making you plan your Tuesday around a chicken thigh for nothing. Salt the night before, sauce it at the end, live your life.

Exactly. The 24 hour thing isn't harmful, it's just a scheduling tax with no payout. Acidic marinades can even go mushy on the surface past a point.

This explains why my mother's tandoori-style chicken always gets slashed deep before marinating. She was manually solving the penetration problem before food science wrote it up.
