would like to buy raclette grill (separate thread asking about models). However, I can't find the cheese in any of our local supermarkets so no point in investing in a grill I can't use. Is it a seasonal thing? Otherwise, where can I get it? I believe Costco does it but not going to renew my membership just to buy cheese! Have tried M&S, Tesco, Sainsbury, Aldi..... Or, anyone used any other cheeses which melt in the same way? Thanks.
