on Kitchen Nightmares with Chef Ramsey, one restaurant used butter on their dessert display... it was on a brownie to look like ice cream... Chef Ramsey found it "effin" unbelievable!"
I can see how that would work - we have a family joke about a time, many years ago, while flying, my sister was served a little cup of whipped butter and she thought it was whipped cream and downed it before my parents could stop her (yeah she was like that) - the look on her face was priceless to the family. Served her right for thinking she was going to eat dessert before her dinner.
