Welcome to Minecraft Foraging!
This mod adds several materials which can be used to craft and cook helpful foods and brews.
In order to find the new items in your worlds, begin to punch grass and the items will drop randomly, some are rarer than others. You will also need to craft mortar and pestles in order to produce most of the powders and extracts used to make the foods and brews.
There are also a couple decorative/storage blocks included.
I decided to rename the mod to Minecraft foraging, because I believe that's the direction that the mod is going.
