Fried mushrooms are a food item and cooking ingredient. They can be created by cooking sliced mushrooms on a range or fire at level 46 Cooking, which if successful grants 60 Cooking experience and creates a bowl of fried mushrooms and if burnt produces worthless burnt mushrooms. Alternatively, they can also be obtained as a drop from Ankous.
As a cooking ingredient, they can be combined with fried onions to create mushroom and onion at level 57 Cooking. While this grants no experience, it does not require a range or fire to do so and the it heals 10 life points more than the two ingredients eaten separately. Mushroom and onion can be used at level 64 with a potato with butter to create the highly desirable mushroom potato for 55 experience.
