Score the ribeye against the grain, to know how to cut it after it cooks.
Season all sides of the steak with salt and pepper and press it into the steak. Then, pour on a tablespoon of truffle oil and rub that along all sides of the steak. Sprinkle on the blackened seasonings and press that into all sides of the ribeye.
Place the steak on a plate and into the freezer for 30 minutes.
When the time is running out, get your grill preheated and greased with some corn oil.
Grill your steak for about 5 minutes per side, if it came from the freezer. Adjust the timing depending on how well done you like the steak cooked.
Let the steak rest for 10 minutes then cut against the grain, where you scored the ribeye earlier.
