Did you know…?
…that ‘bakers’ dozen’ (13 rather than 12) was cooked a lot earlier than you probably think.
Hundreds of years ago English bakers would often cheat their customers by baking air pockets into the loaves of bread, making them lightweight. In 1266 the government passed a law which punished the bakers who sold underweight bread. To be sure they were selling enough bread to meet the new regulations, the bakers started giving thirteen loaves for every dozen a customer ordered.
