Raw potato

Potatoes can be picked from fields, and they heal little per every bite. However, cooking them and then putting various toppings and stuffings in it can make it heal much more. At first, all you can do is bake the potato, making it heal a bit more. When you achieve cooking levels though, you can stuff it with cheese, butter, egg, tomato, and even tuna at high levels. The current potatoes that can be made are:
