4: Make a top layer with the remaining potatoes. Salt lightly.
5: Preheat the oven to 390°F (200°C). Pour 200 ml liquid cream into a saucepan, salt and pepper, then bring to the boil on medium heat.
6: Turn down the heat, add 200 g Mont d'or cheese in small pieces and beat into the cream with a whisk until melted.
7: Pour this mixture over the dish.
8: Bake for about 30 minutes until the top is nicely browned.
Remarks
Mont d'Or is a delicious seasonal cheese that I particularly recommend for this recipe, but if you don't have any, use another cheese you enjoy, preferably a "soft paste" type.
