When I think of frost, I think of little ice droplets on the windows or grass. But the term is used deceptively all around us. I mean, to start, there's the cereal: Frosted Flakes and Frosted Mini-Wheats. But I think this was an aftermath of frosting on a cake (which, I must ask, I'm not convinced ever had its roots in frost). Not that I have anything against the item, as evidenced by its frequent use in many forms in our Bistro. I just think there's a better term. We flock a tree to get a snowy look. Let's instead "flock" our cakes and cereals.
Moving on to icing...well, maybe not. I suppose you get the idea.
