Cooking the base: Spread this mixture on a baking tray covered with baking paper, forming a uniform rectangle. If available, use a silicone sponge cake plate. Cook for 25 minutes.
Filling and assembly: Once the base is cooked, let it cool. Then arrange the slices of ham and the sliced raclette cheese on the surface.
Rolling: Gently roll the mixture up to form a sausage. Make sure the potatoes are cool enough before rolling them to prevent the roll from breaking.

Choose potatoes that hold up well to cooking, such as steamed salad varieties or fried potatoes.
This recipe is versatile and allows you to vary the seasoning according to your tastes, such as courgettes, aubergines or mozzarella.
