Why YSK: When you cook meat, any water on the surface must first evaporate before much browning can occur. You want to get as much of a Maillard reaction as possible in the limited cooking time you have before the meat reaches the correct internal temperature. Removing the moisture first means that the heat of the cooking surface isn’t wasted on evaporation and can instead interact with the meat to form the complex sugars and proteins of the Maillard reaction.
My parents ALWAYS marinate their steaks in a ziplock bag of liquid marinade, and subsequently cook them to a rubbery puck of grey meat. Suggestions to change their ways is futile - Americans don’t like being told they bbq incorrectly…
I did this on Sunday, but it was cooked maybe medium rare. I haven’t cooked a lot in my life. What should I do if I want to marinate next time?
Honestly, I’ve stopped seasoning my steak beyond salt and pepper and wouldn’t personally marinate anything other than something like a skirt steak for fajitas anymore.
If I were to marinate again, I would pull the steak out of marinade and let if drip dry over a towel for 30 minutes or so (or as long as I had patience for - I’m guilty of allllllways cutting corners).
