Julia Child's Scalloped Potatoes

2 pounds russet potatoes

A fireproof baking dish about

10-inches in diameter and

2-inches deep

1/2 clove garlic

4 tablespoons butter

1 teaspoon salt

1/8 teaspoon pepper

1 teaspoon fresh thyme

1 cup grated Gruyere cheese, grated

1 cup boiling milk

Preheat oven to 425 degrees F.

Peel the potatoes and slice them 1/8 inch thick. Place in a basin of cold water. Drain when ready to use.

Rub the baking dish with the cut garlic. Smear the inside of the dish with 1 tablespoon of the butter. Drain the potatoes and dry them in a towel. Spread half of them in the bottom of the dish. Divide over them half the salt, pepper, thyme, cheese, and butter. Arrange the remaining potatoes over the first layer, and season them with salt, pepper and thyme. Spread on the rest of the cheese and divide the butter over it. Pour on the boiling milk. Set baking dish over heat and when simmering, set in upper third of preheated oven. Bake for 20 to 30 minutes or until potatoes are tender, milk has been absorbed, and the top is nicely browned.
