-- CANNED FOOD
-- Introduces new food types to add some variety. All of them rely on glass bottles
-- from the default vessels mod, which otherwise sees very little use. In vanilla game,
-- at least 4 new types will be available, two of which will also turn inedible items
-- into edible food. With farming (redo) and ethereal, pretty much anything that can
-- be harvested can also be canned.
