Scalloped Potatoes

Ingredients

4 or 5 russet potatoes
1 onion
1 1/2 cups heavy cream (or whole milk)
butter       
salt and pepper
1 cup grated gruyere cheese
4 tablespoon flour


Directions

Peel and slice potatoes 1/8 inch thick
Chop onion

In a pan, put 3 tablespoons flour, add 1 1/2 cups cream (or milk) and keep stirring to heat.
Spray a pyrex dish, layer potatoes, chopped onion, a few dots of butter, some of the grated gruyere cheese and add a little cream. Keep layering this way, until you are close to the top. Make the gruyere cheese the last layer.

Put in oven covered at 350 degrees F and cook for one hour. It should be bubbling by then. Uncover dish and continue baking until brown on top.
I generally put a silver foil tray under the scalloped potatoes, sometimes the bubbling is a bit active and can drip into the bottom of the oven.
