To cook a dish, you need to have it chosen in your Recipe Book. Both in Home view and in the LIVE SHOW battle view, you can access your Recipe Book. To choose the recipe:

1. Click RECIPES.,
2. Click the chosen recipe.,
3. Click SERVE.,

Then, when you leave the Recipe Book view, hit the COOK button. Once you draw three icons of the dish you chose - voila, it's been cooked! Remember: you can choose a separate dish for your HOME restaurant, and the LIVE SHOW battle! Always check which recipe is active.
