1. Open the menu and you can see many different dishes, as shown below.

Color is the existing ingredient, and gray is not the beginning.

First, prepare all the materials you need (purchase or exchange)

The gray "Development" changes color, and you can click-"Development Success"

2. After that, "development" became "upgrading". To upgrade the menu, you need ingredients and cooked dishes (100), so don't sell cooked dishes every time, haha. . . ? As long as the mouse moves to the "upgrade" button, you can see how many pairs can be upgraded without clicking ~

You must develop more recipes so that you can have many choices when cooking next time ~!
