I am with the "no sauce" is the best guys.
For a good steak, all I add is some season salt and toss it on the grill.
Now for the Blasphemy.
Tonight I cooked up a couple fine Rib Eyes on the grill. Brought them in, the wife used ketchup on hers. I still shudder thinking about it. She was raised all wrong and I have been trying to straighten her out ever since I married her.
If a steak isn't good enough to eat without a sauce to hide the flavor, don't eat it!
