Say you find a recipe called Roast Chicken with Forty Cloves of Garlic. The instructions read"throw everything in a slow cooker and wait four hours," snd say that the garlic cloves turn out really really good - particularly smeared across a fresh sliced French baguette. And say that after you’ve dreamily chewed your way through half a loaf, your husband yelps and says "Hey! I've only had two cloves!" and you look down and discover that you've eaten the other 38.
That night, you just might just find yourself sleeping by yourself on the living room sofa. For health and safety reasons.
It's just like French onion soup. Only louder.
