A cooking utensil, for example a fork, for measuring and indicating the internal temperature of food. The utensil includes a hollow housing forming a handle (2), fork tines (5) extending from the handle (2) for inserting into food for manipulating it. The tines (5) terminate in a sharp tip (6) to facilitate penetration of the food. Mounted within the tine, toward the tip, is a temperature sensing element such as a thermistor, which varies, that is, by varying its resistance according to temperature. A power source and control circuit are mounted within the handle (2), and a temperature indicator (10) such as a light emitting diode (LED) is mounted on an outer face of the handle. A circuit interconnects the temperature sensor, power source, and LED so that current flow varies with the temperature of the sensor and thereby indicates the temperature within the food at the tip of the fork tine.
