Buy OSRS Sliced mushrooms
Sliced mushrooms are a cooking ingredient in Old School RuneScape. They are made by using a bowl with a mushroom while a knife is in the inventory. Slicing takes no Cooking level and gives no Cooking experience, so any player can make them.
Their main use is training Cooking. At level 46 Cooking, sliced mushrooms can be cooked on a fire or range to make fried mushrooms. Each success gives 60 Cooking experience. Fried mushrooms heal 5 Hitpoints when eaten. They can burn into worthless burnt mushrooms, but burning happens less often at higher levels and stops at level 90 Cooking.
Sliced mushrooms also lead to bigger recipes. Fried mushrooms combine with fried onions at level 57 Cooking to make mushroom and onion. That mix can then be added to a potato with butter at level 64 to make mushroom potatoes.
Sliced mushrooms are a members-only item. They are tradeable and noteable, but they do not stack and cannot be eaten on their own. A spawn can be found in Darkmeyer in Morytania. Players who want fast Cooking experience or ingredients for mushroom potatoes will get good use out of this item.
