Prepare the Kamado BONO grill for indirect cooking. Light the charcoal with a starter, place the cast iron grates, and wait until the temperature reaches 170 degrees Celsius. Adjust the top and bottom air vents to maintain a consistent temperature. Place a cast iron frying pan in the grill, add oil, and add butter. Add the washed and dried potatoes.
Fry until soft for about an hour, turning with herbs and garlic.
Season with salt and spices. Then lightly crush each one and grate hard cheese.
