You're more than welcome to visit ! For this cheese dish (called 'raclette'), anywhere in the south-western canton of Valais will do if you make it over here. Other parts of the country make it differently, by putting slices of cheese into tiny frying pans and cooking it on a table top grill. Also nice, but not the same. Good luck if you try it at home! Making it in front of the fire is trickier than the electric or gas grills that cook the cheese from above, but it's a lot of fun by a fire. Keep the stone cool by either having several and swapping them out, or by rinsing it with cold water every so often. If the stone gets too hot, the entire cheese will melt into a greasy mess. I don't know how easily you can find an appropriate cheese, but I'm sure something will work out .
