A nifty packaging design that doesn&rsquot make a mess when mixing several ingredients. Individual serving packets of butter and maple syrup are folded in the middle to break a seal, releasing the contents, thus allowing us to spread margarine on bread, or dressing on salad without getting our hands dirty. Though these packets were first developed in america, by today japan produces more of them, more than any other country. There are also dual packets, with margarine on one side and jam on the other. A japanonly variation would be ketsup and mustard in one packet.
