I have a 'frig full of sour grapes and let me tell you, it was a surprise to me to be reminded by Wikipedia that the expression 'sour grapes' refers to disdain for something you can't have anyway. Sour grapes are not only something I can have, they seem to be the only grape I can have, courtesy of a conspiracy by my local grocery stores.
What I want to know is, what can you do with sour grapes? It's not like eating them straight is an option.
Can I add sugar and bake them into a pie? Float them in a bowl as a centerpiece? Pitch them at people who annoy me?
Maybe I should take advice from Epicurious, and roast them.
