Ingredients

  • 1 kg potatoes, peeled and thinly sliced
  • 2 onions, finely chopped
  • 100 g anchovy fillets, drained and chopped
  • 300 ml heavy cream
  • 150 ml milk
  • 50 g butter
  • Salt, to taste
  • Black pepper, to taste

Steps

  1. Preheat the oven to 200°C (392°F). This temperature ensures the gratin bakes evenly and achieves a golden crust.

  2. In a large frying pan, melt 25 g of butter and sauté the chopped onions over medium heat for 5-7 minutes until they become translucent.

  3. In a greased baking dish, layer half of the sliced potatoes, followed by half of the sautéed onions and half of the chopped anchovies. Repeat the layers.

  4. In a separate bowl, mix 300 ml of heavy cream, 200 ml of milk, 1 teaspoon of salt, and 1/2 teaspoon of black pepper. Pour this mixture over the layered potatoes.

  5. Dot the top with the remaining butter and bake in the preheated oven for 45-50 minutes, until the top is golden brown and the potatoes are tender when pierced with a fork.

  6. Let the gratin rest for 10 minutes before serving. This helps the layers set, making it easier to serve.

Why this works

The combination of thinly sliced potatoes and anchovies creates a rich, savory flavor profile, characteristic of Nordic cuisine. The cream and milk mixture, measured precisely at 300 ml of heavy cream and 200 ml of milk, provides a luscious texture, allowing the potatoes to absorb flavors while keeping them moist during baking. The use of a high baking temperature at 200°C (392°F) is crucial; it not only helps achieve a beautifully crisp top but also ensures even cooking throughout. If the gratin appears too dry while baking, you can add a splash more milk or cream to prevent it from burning and to maintain moisture. Conversely, if it seems too watery, consider increasing the baking time by an additional 5-10 minutes to help evaporate excess liquid, ensuring that you achieve the perfect consistency. The time spent resting for 10 minutes post-baking is equally important, allowing the gratin to set properly, which enhances the presentation and serving experience. This dish embodies both tradition and flavor, making it a delightful centerpiece for any gathering.
