Christmas Eve is the Belgian equivalent to American Thanksgiving – but with gifts. There’s often turkey involved in the main course but a piece of game or a nice roast are common as well. Complementing the meat are often mashed potatoes or pommes duchesse, elegant little swirls of potatoes that have been brushed with egg yolk before entering the oven to attain their crispy golden-coloured jacket.
Preheat the oven to 425°F. Rub the potatoes with olive oil, sprinkle them with salt and pepper, and prick them with the tines of a fork. You can lay them directly on the oven rack or place them on a baking sheet. Cook the potatoes for 45 to 60 minutes, until their skin is crispy, and sticking one with a fork meets no resistance.
