For sure! The balsamic vinegar is a great addition. With some steak, it just does something beautiful. It feels so strange, I have been doing it like that my whole life, so whenever I eat steak without it, something always feels lost.
I love the addition of mustard though! When you cook any meat with mustard, the condiment or the powder, something beautiful happens. A roast in the oven coated with mustard and then the gravy made with ample of the meat-juice-mustard-sauce, is something heavenly!
