This recipe came from an estate sale. I obtained it when I purchased the family collection from the Brunson Estate in Midlothian, Texas in 1990.
Ingredients:
4 large russet baking potatoes peeled and sliced 1/4 thick
1 garlic clove peeled and crushed
1 tablespoon softened unsalted butter
1/2 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
3 tablespoons freshly grated parmesan cheese
3 tablespoons grated gruyere cheese
1-1/2 cups whipping cream
Directions:
1. Place rack in top position of oven then preheat oven to 350. 2. Put potato slices in bowl of salted water to prevent discoloration. 3. Firmly rub an oval gratin dish all over with garlic. 4. Let dry a few minutes then rub bottom of dish with butter. 5. Drain potatoes and pat dry with paper towels. 6. Arrange a layer of potatoes slightly overlapping in bottom of buttered dish. 7. Season with salt and pepper then sprinkle with a little of each of the two cheeses. 8. Continue layering potatoes and cheese seasoning each layer and finishing with cheese. Drizzle cream along the sides of the dish so cheeses are not displaced. 9. Bake uncovered until cream has been absorbed and top is crispy and golden. 10. Let stand 10 minutes before serving.
