Has anyone besides me had this occasional problem?
Sometimes when I whip heavy cream in a metal bowl (not sure of composition), I get small flecks of gray material in the whipped cream. The flecks feel fatty (creamy) to the touch and look like the color of the metal bowl. It seems like the flecks are bits of the metal that have rubbed off (!) into the cream.
I've had this happen using a hand whisk and using a hand-held electric mixer. (I have not had this problem when whipping cream in my Kitchen Aid, however.)
Can anyone explain this? Is the bowl of cheap material? Not clean enough (yikes)? Other ideas?
