1. A refrigerator comprising
a fresh food compartment for storing food, the fresh food compartment comprising a temperature sensor disposed therein;
a temperature-controlled drawer positioned within the fresh food compartment; the temperature-controlled drawer including:
a display including a plurality of lights each indicative of a different storage temperature for the temperature-controlled drawer, and
an input device for allowing a user to selectively illuminate the plurality of lights,
wherein the temperature-controlled drawer is configured to have a temperature that is a predetermined temperature differential from a temperature in the fresh food compartment during steady state operation of the refrigerator; and
a cooling system configured for introducing cold air into the fresh food compartment; and
a controller for controlling the cooling system of the refrigerator, the controller configured to have at least two modes, wherein
in a first mode the controller controls the cooling system to achieve a desired temperature within the fresh food compartment without respect to the temperature in the temperature-controlled drawer,
in a second mode the controller controls the cooling system to achieve a desired temperature within the temperature-controlled drawer based on the temperature sensor in the fresh food compartment and the predetermined temperature differential, and
a flow path for cold air flowing to the temperature-controlled drawer is free of a damper.
