2 cupsof 10% cream or half & Half
1tsp salt
1/2tspfresh ground pepper
a pinchof ground nutmeg
2cupsof grated cheese (gruyère or comté or Maréchat)
Instructions
Rub a cast iron pan or gratin dish of about 10 inches with half a clove of garlic. When dry, butter the inside of the dish.
In a large saucepan, combine: sliced potatoes, half a clove of garlic, the shallot, the combination of milk and cream or 10% cream, salt, pepper and nutmeg. Bring to a simmer, reduce the heat a little and simmer for 5-10 minutes, no more.
Remove the shallot and the garlic clove. Transfer the mixture to your prepared cast iron pan. Here, you have two options: 1- Press well so that the potatoes are covered with the cream.2- For a more rustic look (such as the one you see here) and crunchy bits, layer the slices of potatoes vertically (like Hasselback potatoes) until you've filled up the pan with potatoes. Then transfer the cream mixture.
Top with cheese and bake. Cook for about 35-50 minutes until the gratin is nicely browned and the potatoes are well cooked.
Let rest for about 10-15 minutes, while your guests join the table. Bon appétit!
