Peel 5-6 potatoes and slice them the way you want. Pour 1 teaspoon of carbonate powder into a pot of boiling water, boil the potatoes for 5 minutes. After draining the potatoes and removing their water with a cotton cloth, drizzle olive oil over the potatoes you have placed side by side on a baking tray. Sprinkle with salt and cajun seasoning. Bake at 180 degrees (top and bottom) for 40 minutes, then on the upper grill for 10 minutes at 200 degrees.
Enjoy your meal.
