I love smoked salt. Used some last night when I roasted some pecans. Excellent.
My serious answer about steak toppings:
I don't care for seafood toppings on steak. On the side is fine.
I don't go for the "nothing on my steak" deal though I understand it. Sometimes, all I want is a little salt and pepper. Sometimes, I like a brown butter parsley sauce. Sometimes, I like a blue cheese butter pat on top. Blue cheese and beef are a great combo. On occasion, a little bearnaise floats my boat. Sometimes, I use Cavender's rather than salt and pepper. Depends on my mood and the eaters involved. Steaks have been served with various sauces and toppings for a gazillion years. If you like it that way, eat it that way.
