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

A food processor will be used whenever food needs to be chopped, but will not be used at other times. There are food preparation surfaces that are slightly better than a food processor, but food processors still have advantages. They speed preparation of food that needs to be chopped, especially for Sims with lower Cooking skill. Using a food processor keeps the counter it sits on clean, even when used by a sloppy Sim. Also, it appears that food processors don't need to be cleaned.

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.
