we just love raclette. I lived in Switzerland as a teen and raclette and fondue were my favorites. You can get raclette cheese at Waitrose, have never seen it at any of the other grocery stores. When we have raclette I serve it with boiled new potatoes, pickled baby onions, the Swiss/French cornichon gherkins and I also buy a selection of dried meats such as salami, parma ham, air dried beef. Like fondue it is a fun dinner and so easy to clean up.
Have fun.
