Ingredients:

• Some butter for the baking dish at room temperature
• 3 cups heavy cream
• 1/4 cup horseradish ( the grated kind you buy in the jar. It's not the fresh root you grate at home. Nor is it the creamy pre-made sauce you can buy at the store. )
• 1/4 teaspoon ground nutmeg
• kosher salt and black pepper
• 3 lbs  potatoes (russet are the best) peeled and thinly sliced

Method:

1. Heat oven to 375° F. Butter a shallow 3-quart baking dish. In a large bowl, combine the cream, horseradish, nutmeg, 1 1/2 teaspoons salt, and 3/4 teaspoon pepper. Add the potatoes and toss to coat.
2. Transfer the potato mixture to the prepared baking dish, pressing gently to submerge the potatoes. Cover the dish with foil, place on a rimmed baking sheet, and bake for 25 minutes. Remove the foil and bake until the potatoes are tender and the top is golden, 50 to 65 minutes.
