Golden Carrot

A golden carrot is an item used as a brewing ingredient for making potions of night vision.

Trivia

 * Golden carrots being used for potions of night vision is based on the common misconception (promulgated by the British government during WW2 (which was a likely occurrence given the amount of rationing at the time). ) that eating carrots can improve one's vision; this is only true if one has vitamin A deficiency.
 * Golden carrots may be the most beneficial (magical effects excluding) food item so far: their effective food+saturation value is 20.4 - just a bit less than that of meat (20.8), and they are 1.5 times as nourishing, meaning you'll spend a greater fraction of time in saturated state with health regeneration on.
