ngl grilling isnt as foolproof as my method ive been developing for a couple yrs now
get your steak to room temp and then s&p
throw it in a hot cast iron on stovetop w butter and smashed up garlic cloves for about 1 min/side, basting the whole time
then put the cast iron into 400degree oven, 5-7mins depending on how you like it
take it out and put it on cutting board, let it sit for about 10mins
