Food processor

A food processor is a small appliance found in The Sims, The Sims 2, and The Sims 3. In the former two games, it costs §220, and will speed preparation and add hunger value to food when used.

The Sims
In The Sims, it's known as the XLR8R Food Processor, and is considered to be the best food preparation surface. It is always used for single and group meals, unless the Sim preparing the meal cannot get to it.

The Sims 2
In The Sims 2, it's been upgraded to the XLR8R2. The XLR8R2 speeds preparation of foods that need to be chopped, especially for Sims with lower Cooking skill, keeps the counter it sits on clean, and apparently doesn't need to be cleaned. So, while there are food preparation surfaces that are slightly better, it's still worth having.

Kitchen & Bath Interior Design Stuff added the Carrot Chopper Deluxe, which is slightly more expensive (§260 instead of §220).

The Sims 3
In The Sims 3, the food processor is called the Ingredient Eviscerator 235X, and it costs §280. It can be used to make baby food out of leftovers. Sims can get one free through the Culinary career.
