Throwing a raclette party is a very memorable and enjoyable experience. First you will need to find a great place to buy raklette cheese. Once you have figured that out, run to the grocery store or local farmers market and pickup the freshest vegetables you can find. The most popular items that people like to grill with their cheese, are peppers, potatoes, onions and squash. Next you'll want to pick up a few bottles of wine (to drink as well as use as an ingredient) and some kirsch and make sure you have herbs and spices on hand for subtle flavor if your guests are confindent enough to mix them in. Some good ones are thyme, sage, parsley, paprika as well as other additions including, fresh lemon juice, worschershire sauce or hot sauce.
Set the grill up ahead of time and then chop the veggies and cheese so they are easily accessible for the guests to throw in their pans. Lay everything out just before you turnthe grill on. Open the wine and let the night progress as it will.
