Food was easier to talk about, so if Lucy wanted them to meet, this was probably the best way. Emma decided to start with the easiest to explain and work from there. "Disco fries are the US's answer to poutine: fries with cheese and gravy." And one of Pyro's favorites, so she moved on before that could refresh the hurt that never really faded.

"Latkes are a kind of potato pancake, often served with apple sauce or sour cream. Aligot is... a cross between mashed potatoes and cheese fondue. Gratin dauphinois and tartiflette are both baked dishes; thinly sliced in cream, or cubed with cheese, lardons – or bacon – and onion, respectively. Then there's raclette, which is actually the type of cheese, but you can set a wheel of it by a fire until it melts, then scrape the melted part over potatoes, pickles, charcuterie, and that's also called raclette. It's from racler, to scrape."

She summed up by counting off her fingers. "So that's deep fried, pan fried, puréed, casseroled, or bathed in melted cheese."
