How to Make It

  1. Preheat oven to 375°F.
  2. Combine milk, potatoes, bay leaf, 1/4 teaSpoon salt, and garlic in a large saucepan; bring to a boil. Reduce heat and simmer 5 minutes or until potatoes are almost tender.
  3. Drain in a colander over a bowl, reserving 1/2 cup milk mixture.
  4. In the milk mixture, add nutmeg and simmer for a few minutes. Before removing from the stove add mustard, stir well. Set aside.
  5. In a 12-inch nonstick frying pan set to medium, heat 4 TableSpoons of the olive oil. Add the leeks, a 1/4 teaSpoon of the pepper and a 1/4 teaSpoon of the Sea Salt with herbs. Stir to coat the leeks with the oil. Stir occasionally until the leeks are tender - about 4-8 minutes. Remove pan from heat; place leek mixture in a bowl.
  6. Arrange half of potato slices in a single layer on the bottom of a gratin dish; top evenly with half of leek mixture. Sprinkle with 1/2 teaSpoon Sea Salt and 1/4 cup of Gruyère cheese.
