An electronic visual food probe for insertion into and viewing of the interior of a body of food. The distal end of the stem has one or more openings that collectively allow light into and out of the cavity, the opening(s) exhibiting a degree of radial displacement. A light source in the stem illuminates the interior of the food exposed to the opening. An electronic image sensor receives the light reflected from the interior surfaces of the food proximate the opening(s) and generates an elongated color image of the reflected light. An electronic display system displays the elongated color image.
