A cooker.
Each Cooker has a certain maximum number of cooking attempts (from 1 to 5). Cooking multiples of a recipe in a single instance will only use one cooking attempt, so this is the recommended method of getting the most out of a Cooker as long as you have enough ingredients.
Do so at your own risk, because if the skill check is failed you lose all of the ingredients.
A cooker being repaired can explode if the repair attempt using Mechanical fails. The image to the right shows a safe, though untested, way to avoid being caught in such a blast.
