Game guide:Completing the Cooking skill challenge

There are 3 Challenges for the Cooking Skill. Sims with the Natural Cook trait can complete them more easily.

Star Chef
Star Chefs have prepared at least 50 meals, so they clearly know their way around the kitchen. The dishes they prepare are more pleasing to those that eat them.

How To Unlock: Prepare 50 meals.It is easier if your sim is not a vampire or simbot, because vampires only need to drink plasma and simbot only eat scrap.

World-Class Chef
World-Class Chefs have prepared at least 75 dishes and are masters of the kitchen. World-Class chefs are known to prepare meals significantly faster.

''How To Unlock: Prepare 75 meals. It is easier if your sim is not a vampire or simbot, because vampires only need to drink plasma and simbots only eat scrap.''

Menu Maven
Menu Mavens have learned to prepare all the recipes. Recipes are earned by improving the cooking skill and can be purchased at the bookstore. Menu Mavens prepare higher quality food.

''How To Unlock: Your sim must master the cooking skill and buy every recipe from the bookstore and read it. You need to learn all 28 recipes from the base game. Recipes from World Adventures do not count.''
