Duchess Potatoes (Pommes de Terre Duchesse)
- 4 cups (1 L) mashed potatoes, heated
- 1/4 cup (60 ml) melted butter
- 2 egg yolks, beaten
- 1 tsp (5 ml) Dijon-style mustard
- Salt and white pepper to taste
Combine all the ingredients in a bowl and stir to thoroughly combine. Make mounds or patties on a greased baking sheet and decorate with a fork if desired. Alternately, you can pipe the mixture, using a pastry bag with a fluted tip, into any shapes you desire. Bake in a preheated 400F (200C) oven until golden brown. Serves 6 to 8.
