Idiom for today: The proof is in the pudding…
The “proof is in the pudding” is better understood when it is said in its entirety. “The proof of the pudding is in the eating.”
The shorter version came into use in the 1920’s. Simply put it means only through the actual experience can the value of something be tested.
This proverb dates back at least to the 14th century as “Jt is ywrite that euery thing Hymself sheweth in the tastyng”, and William Camden stated it in 1605 in Remaines of a Greater Worke, Concerning Britaine as “All the proofe of a pudding, is in the eating”, per Rogers’ Dictionary of Cliche and the Oxford Dictionary of Quotations.
“How do you know if your grandmother’s recipe for banana pudding is good?”
“The proof of the pudding is in the eating.”
