Potatoes are kept in the dark, in a cool and dry place, in containers or wooden boxes, while periodically checking them and eliminating any sprouts. You can clean them under running water and brush away the earth. Depending on the recipe, you can cut them into slices, wedges, dice or sticks. You can cook them in boiling water for 30 minutes, in the oven at 200° for 30-45 minutes, you can fry them in oil at 180° or cook them in a pan after blanching them.
