"…I just don't get Potions," said Harry at length. "I can make them okay, but I don't understand why I'm doing what I'm doing."
Ju beamed.
"People rarely ask that question," he said. "Most wizards and witches are content to simply know how to brew a potion and leave it at that."
Chuckling, Ju looked around the music room.
"Looks like Jack isn't going to show up for a while," he said. "If you like, I can give you two a primer on Potions. Keep in mind I'm American and not a teacher, so I don't give a flip about tradition or British school standards."
Harry recalled Ju's rant over cauldrons and nodded.
"In order for Potions to make sense, you need to think soup," Ju started. "Because that's what a potion is: a soup. I mean, you make it in a pot full of liquid over a fire and you shove a bunch of ingredients in it and simmer them all together to mingle the 'flavors'. If that's not a soup, I don't know what is."
Harry grinned at the irreverent description.
