The Rat Connoisseur is a new character introduced by the Grow a Garden Kitchen Storm update. Compared to Chris P, this giant rat has a more refined style, as it is dressed in a black suit, complete with a top hat and a monocle. You can feed him mutated food to get diverse prizes, all the while being appreciated by the connoisseur.
This guide explains how to cook mutated food items, serve them to the Rat Connoisseur, and collect rewards.
About the Rat Connoisseur in Grow a Garden

The Rat Connoisseur is a food taster and reviewer seemingly inspired by the rat chef Remy from the Ratatouille movie. He can be found opposite Chris P in the middle of the island.
Unlike Chris P, the connoisseur doesn't demand specific food items in Grow a Garden. You can give him any dish as long as it contains one or more Mutations. Once the NPC accepts your mutated food, they will offer you three choices, from which you can select one as a reward.
The higher the number of Mutations in a food, the rarer the reward choices presented by the Rat Connoisseur.
How to give mutated food to Rat Connoisseur

In Grow a Garden, you can make mutated food by putting mutated crops in the cooking pot. The meter above the pot will show you your chances of getting a dish with Mutations. This should ideally be between 96% to 100%.
When cooking, only use those crops as ingredients that have at least five Mutations. This will drastically enhance your chances of getting a mutated dish, including when you're following Transcendent or Prismatic recipes.
Once the mutated food is created, offer it to the Rat Connoisseur by selecting the "Try this food I cooked up!" option. The NPC will then open the reward selection screen, from which you can choose a single item.
