I know man, I know. I like just about all creams other than white sauce. I can dig sour cream, cream cheese, creamy mashed potatoes, and the list goes on.
There's just something about sitting at a Japanese steakhouse across from a morbidly obese family, all of which ordering double white sauce, that steers me in the mustard/ginger direction. The worst/best is when said obese peeps ask the chef to squeeze the white sauce directly onto their plate, because, you know, 2 saucers full just isn't enough for 200 lb 12 year old boy chad and his 325 lb parents, Norma and Earl.
