Much like what I did in my Steaked Salad recipe, this takes it to a new level and is good for small cuts of steak...such as that from buffalo.
Buffalo NY Strip steaks, about ¾ inch thick
Salt & Pepper (or Montreal steak seasoning)
...one hour before cooking.......
Remove the steaks from the fridge, quick rinse under cold water and pat dry with paper towels. Trim some of the visible fat off the steaks, about a scant ¼ cup worth, and reserve. Sprinkle generously with salt and pepper or the steak seasoning. Set steaks on a wire rack and let sit for one hour, uncovered, room temperature.
Preheat the cast iron skillet to medium for 5 minutes. Add the reserved fat and "render" it for about 10 minutes, meaning, gently cook the liquifying fat out of the solids. Discard the solids keeping the liquid fat in the pan.
Crank the heat up to medium-high. [For what it's worth, my stoves burners go up to 19,000 BTU so medium-high on mine might be high or medium on yours.] As soon as the fat begins to smoke, add 1 TBS of butter per steak. It will immediately bubble and start to brown. Get ready.....
Add the steaks and try not to get fat burns on your arms doing this; tongs are advised. Sizzle for two minutes; tilt the pan to swirl the fat around.
Rotate the steaks to their sides as seen in the pictures - cook like this for about 30 seconds on each side (lateral ends excluded).
Flip the steak to the uncooked side and cook for an additional minute, tilting the pan to ensure equal fat distribution. When removing the steaks, swirl the top of the steak in the pan quickly to soak up some fat.
