On "Friends", which character made "Mocolate"?

On "Friends," Monica made "Mocolate." The joke appears in "The One with the List," the eighth episode of the show's second season. After Ross and Rachel finally kiss, Ross creates a list comparing Rachel with his girlfriend Julie, while Monica takes a temporary job developing recipes for a strange new product called Mockolate.

Mockolate is described as a completely synthetic chocolate substitute. Monica is hired to turn it into appealing Thanksgiving recipes, including cookies, cranberry cake, and pie. The problem is that the product tastes terrible and behaves strangely. Monica tries to remain professional because she needs the money, even while quietly admitting that the food is almost impossible to eat.

A common mix-up is the spelling: the fictional product is usually written "Mockolate," although the quiz uses "Mocolate." Another memorable detail is that the company fails to receive FDA approval, reportedly because of problems involving laboratory rats. Monica still gets paid, making the bizarre job one of her many early-career misadventures before she returns to professional cooking.
