Hey, I've a pretty smart way to seriously increase your cooking level and make some amazing cash.
This method only requires you to have some start up cash, the more the better, and be able to click a lot, bank, and repeat.
Here it goes, making pineapple pizzas!!!
Zomg, I know what your thinking, "There is no way I'm going to sit around and cook pizzas."
All you do is buy plain pizzas in GE. Also you buy Pineapple rings. Remember, you can post in the forums to try to find a buyer. Once you have all the pizza's made, Sell them max into GE. If they don't sell almost instantly, lower the prices down a little.
Here is the awesome part

You get 45 experience per pizza you make and you make some wicked profit.
I don't have any real calculation's for you guys but here is my status.
I went from 90 cooking to 93 cooking in about one week on and off from this method. Here is the amazing part.
I went from about 4.5 mill to 21m!!!!!!!!!!!!!
I made over 2m each day.
Well glad i could help you guys. + rep if I helped anyone
