How to make
Peel the potatoes and put them in a pot of water or steam them, until they slightly soften.
Remove and place them in a baking pan. Flatten them with a glass. Put butter on each piece. Sprinkle with salt, black pepper and rosemary.
Bake the potatoes in a preheated oven at 390°F (200°C), until a golden brown color is obtained.
The Portuguese-Style Potatoes are ready.
