I HATE Miracle Whip. If I order chicken salad at a restaurant I will ask or taste it before to make sure it is made with Mayo. I only use Best Foods Mayo, but rarely. Never on a sandwich. Only in egg salad, chicken salad or a recipe.
Mayo. NY/NJ born and bred. And for the past several years, a significant portion of that has been Kewpie.
Miracle Whip on sandwiches, mayo in potato salad, etc. When I was little, I loved plain Miracle Whip sandwiches--they went great with Spaghettios! Now I can't believe I ever ate them...
