butter or margarine? I was raised on margarine for my bread, but I'll cook with butter, and sometimes margarine.
miracle whip or mayonnaise? I don't really like either, although I do keep some mayo around for Tuna Salad, devilled eggs, etc.
A-1 or other brand? A good steak has a nice dry rub applied to the outside. Those seasonings, and blood/juices from a medium steak are all I really need, but sometimes I do put a little A-1 on.
soy or teriyaki? I'll cook with soy, but don't like it as a condiment. I make my own Teriyaki.
