Funny, my husband grew up on Miracle Whip & I, on mayonnaise (Cains -- a regional brand that I absoluely LOVE & now mail to my Midwest family members). He used to give me grief about only buying mayo so, afte almost 20 years of marriage, I finally broke down & bought him his own small jar of Miracle Whip. About 3 years later, I finally threw it out, unopened. He hasn't said a word about mayo since. ;-)
We are totally condiment crazy -- really. I like Simply Heinz ketchup (I think it has, like, 5 ingredients -- all of which I can pronounce!). For mustard, we have both dijon style (usually Grey Poupon) and Gulden's. I don't think I'll ever buy a yellow mustard intentionally. We also have a couple of kinds of Robert Rothschild Farm mustards (Raspberry Wasabi & another -- great for dipping with pretzel sticks).
We like Ken's or Brianna salad dressings, Lee & Perrin Worcestershire sauce, good quality oils & vinegars (though no articualr brand). I'm not a huge barbecue sauce fan -- except for a homemade sauce a friend makes.
Catherine C -- I want to be you when I grow up! I've always wanted to try my hand at making my own mayo. I've heard it's absolutely fabulous. I've never quite gotten around to it, though. Maybe some day...
