Kappacasein Dairy is a cheese shop in Borough Market, London, selling cheese toasties and raclette. The cheese toastie puts melted cheese, leeks and onions between slices of sourdough, while the raclette tops potatoes and pickles with melted cheese. The order queue usually takes about 5 to 15 minutes, and the raclette is scraped from a large cheese wheel onto the potatoes. The cheese flavour is strong, so it can taste salty and heavy.
