The Radish is a VegetableFoodItem exclusive to the Hamlet DLC. It can most often be found growing naturally in the ground, but these won't respawn after being picked. Radish can also be Farmed by planting Seeds in a Farm.
Raw Radish restores 12.5 hunger and 1 health when eaten, and takes 10 days to spoil. Cooked Radish restores 12.5 hunger and 3 health when eaten, and takes 15 days to spoil.
