An interesting discovery!

I have suddenly found myself with quite a bit of free time on my hands so I'm rereading Harry Potter and the Sorcerer's Stone. Well, wouldn't you know it, the first dish that Harry is offered after everyone's sorted is none other than our favorite food of all time, potatoes!

"'Mad?' said Percy airily. 'He's a genius! Best wizard in the world! But he is a bit mad, yes. Potatoes, Harry?'" -pg. 123
