Green Caps are VegetableFoodItems. A raw Green Cap will take away a hefty 50 when eaten, while also restoring 12.5 . It has no effect on health. Green Caps can also be used as Crock Pot filler with a 0.5 vegetable value.
A Cooked Green Cap is a Vegetable Food Item made by Cooking a Green Cap on a fire (Campfire, Fire Pit, Dwarf Star, etc.). Unlike its raw counterpart, the Cooked Green Cap will instead restore 15 and take away 1 when eaten, not affecting hunger at all.
