Wikipedia has done it again! It came to the rescue last night when it solved a classic dinner-party question – what is the difference between a cake and a biscuit? The answer is that it’s all about moisture content.
“The difference between a cake and a biscuit is that a cake has a higher level of moisture than the average moisture content of air, whereas a biscuit has a lower level of moisture than air. Hence, a cake will go hard when left in air and a biscuit will go soft.”
What a nugget!
