HP sauce.
Sorry, never use the stuff ! When I BBQ a steak ? It never needs any sauce.
I never use steak sauce.
Left over steak or prime rib only---Worcestershire or A-1, depending on my taste prefeerence for the day.
I prefer my stake naked, no sauce. If it's a good cut of meat, it shouldn't need anything to mask the taste. If you use ketchup on steak, you should be shot.
I've never ate steak so I've never had a steak sauce either. I guess I could put it on eggs or something though. Yeah nah.
I don't eat beef anymore. (It doesn't like. :( ) But I never used steak sauce. If your steak needs sauce someone screwed up.
If I use it at all, it's A1.
