Got hungry at 9:30. Hit the Supermarket and picked up this $6 ribeye. It was about 1/2 - 3/4" thick max.
It doesn't look like much, but I **** you not, this was the best Supermarket steak of my life.
My method if anyone cares:
Pull from supermarket fridge, bring home, salt as quickly as possible (it had about 10 minutes)
Heat carbon steel pan over medium high heat
Cut off a chunk of accessible fat and render in pan
Add some Canola to raise smoke point, 2 cloves of smashed garlic, 2 sprigs fresh thyme to flavor fat - remove when garlic passes golden
Add 2 tbs butter
Get fat to temp, brown edges of steak
After edges are browned, cook steak, flipping every 10 seconds, pressing down on the eye to cook as evenly as possible until it reaches your preferred level of doneness (3 - 5 minutes
Cool on rack for at least 5 minutes uncovered (I've stopped tenting as it ruins crust, even tho crust goes away while resting anyway ime)
Heat same pan with fat over extremely high heat until it just barely starts smoking
Add steak and crust for a long minute each side (I count slowly in my head so it may well be more like 1:10 or 1:15)
Pull, salt, pepper, and eat
Keep in mind, my goal here was an extremely deep, crunchy crust, and I was willing to sacrifice a little 'brown ring' to achieve it. In this case, the crust was deeper, crunchier, and more substantial than I had dared hope for.
I was so pleased with this impromptu $6 ribeye that I went back today to buy another.
