Barley is a grain that can be harvested and made into Grain Mush using
a Grinder. When harvested, the icon will turn into a bushel of the grain.
Barley can be found on the grasslands in the form of grouped brown stalks.
In order to consume it, you will need a Grinder. Click on the grinder without any tools equipped and a GUI will pop up asking what you want to grind. Click on the Barley and it should produce edible Grain Mush.
