An egg potato also called egg and tomato potato, even in the official RuneScape manual, or, in the Cooking level up table, baked potato with egg and tomato) is a food item that can be made by members by combining an egg and tomato topping with a potato with butter. This requires a Cooking level of 51, grants 45 Cooking experience, and does not require a range or fire.
Creating all ingredients from scratch and using them to create an egg potato grants 195.5 Cooking experience.
Like the monkfish and potato with cheese, an egg potato heals 160 lifepoints in a single bite. As such, this is an even more uncommon food than the potato with cheese, as the process to create an egg potato requires a Cooking level of 51 rather than 47, provides 4 less experience, requires several more steps to create, and requires components not available from the kitchen of a player-owned house.
