it'll take roughly 3-4 minutes.
then take it off, soke off the excessive oil, give time to cool down and rest, and EAT IT.
the juices kept inside will explode like no Sasha Grey has ever seen before. dont add anything else. you can try but simplicity = perfection. better use the best meat you can find and follow the technique, then come back here and pour a glass of good old whisky to say thank you based OP.
ps you can use topings like sour cream or high tier melter butter. some fags put sliced jalapenjos with the meat. but its up to you. better perfect the basics then master your own.
