McDonald's Mustard Packet Complete Information
A McDonald's Mustard Packet costs $0.10 and carries 0 calories, which makes it both the cheapest item on the entire McDonald's menu and the lightest.
Nothing else McDonald's sells comes in under it on price. It is the same yellow mustard that goes on the Hamburger and Cheeseburger builds, so a packet is really a way of getting more of what is already on the burger. At 0 calories it is a rounding error next to a dip cup: the 110 calorie Creamy Ranch is more than a hundred times it. For anyone tracking a meal closely, mustard is the condiment that costs nothing in either sense. Pair it with a Hamburger, a Cheeseburger, or Small French Fries if you like mustard on fries.
