Stuffed potatoes

Wash the potatoes, and then cook them in boiling water for about 15 minutes (The potatoes have to be cooked but still firm).
Drain them, cut the top and scoop out the inside of each potato.
In a bowl, mix mashed potatoes, the terrine with Roquefort, the cream, an egg, salt and pepper.
Stuff the potatoes with the mixture and sprinkle with breadcrumbs.
Butter the aluminium sheets.
Put one potato on each aluminium sheet, dot with the rest of the butter, close hermetically and cook for 15 minutes in the oven at 180°, or in the barbecue.
Open the aluminium sheets and serve with raw seasonable vegetables.
