4        lbs. White Potatoes, peeled and diced
2        cups Heavy Cream
¼       pound Butter
3        Tablespoons Kosher Salt
1        Tablespoons White Pepper
1        Egg, beaten
8 oz.  Aged White Cheddar Cheese
2        Sheets Puff Pastry

Boil potatoes until tender, about 20 minutes. Drain and add butter, cream, salt, pepper and cheese. Mash together to a smooth consistency. Spread potatoes on a cookie sheet and cool until firm.

Thaw puff pastry and cut each sheet into 6 even squares.

Divide Potato mixture evenly onto center of each pastry square (you may have potatoes left over). Fold the four corners of the pastry over the potatoes. Brush the edges of the pastry with the egg and pinch closed to form a pyramid shape. Bake in 350° oven for 20-25 minutes or until a deep golden color is reached. For a variation, you can add onions, shrimp or vegetables to the potato mixture.
