How to make
Wash the potatoes very well without peeling them, then halve them lengthwise. Place them in an oven dish, covered with baking paper.
Put them in a preheated 390°F (200 °C) oven and let them bake for a little over an hour. Toward the end, sprinkle them with spices and leave them to sit briefly in the still warm oven.
They can be consumed with their skins, or peeled.
