USA Fedederal law does not allow margarine to be called butter. Same reason the fast food places call it a shake not a milk shake. To call it a milk shake it has to have some percentage of real milk in it. Not some drypowder starch added to water. I believe Cheese has to be 51% milk so I notice the latest fast food commercials "burger king?" refers to it as "cheddar" the word "cheese" is never used in the ad. I belive the only proper legal name for the stuff is, processed amercian cheese food product.
A loaf of bread has to weigh one pound ,or more by federal law. Does butter have to be at least one pound as well?
