Does Kraft taste like it's made with real cheese? No, not at all—but it doesn't have to. Part of Kraft's specific brand of deliciousness lies in it's strangely addictive artificialness, a semi-sweet cheddar flavor with a slight chemical finish that somehow satisfies like no other can, and probably ever will.
