A tip from Lagrange for robust raclette!
The key to great raclette is great cheese! If you can, find a cheese that is labelled AOC (Appellation d’Origine Contrôlée/Controlled Designation of Origin) this means the cheese is certified as made in a specific geographical designation. You can find raclette cheese made in Switzerland or the Savoy region of France.
Apart from the classic raclette cheese, it also can be made smoked or flavored with herbs and spices such as pepper, cumin and white wine. Don't be afraid to mix things up: why not add in a few slices of Morbier or Bleu for a unique fondue experience!
