I have no idea what a “Gucci” is, but the technique described in How to Turn Cheap “Choice” Steaks into Gucci “Prime” Steaks works on the cheap steaks I’ve tried it with.
Massively salt your steaks 15 min – 1 hour before grilling.
That’s it. It should look like this (image from that website):
Don’t use table salt. Use pickling or sea salt – the large grained stuff. Cover both sides of the steak for at least 15 minutes, then rinse it off. Wipe off the moisture, then cook it.
I found the steak to have a slightly salty taste, but it’s like it was marinated. Delicious.
Update: J-walk tried it with mixed results:
It turned out fine. I only salted one steak, so we could use the other as a control. The salted one MIGHT have been a bit more tender, but it could have been a placebo effect. It did not taste salty at all. Bottom line: It does no harm.
