"Flour" is a generic term which represents four different types of flour available in the game and which is crafted by grinding the Ear of Cereals produced from Cereal fields in a Windmill or in a slower Copper Grinder or much slower Grindstone.
Any recipe which states "Flour" as ingredient allows you to use any tier of flour, and each type will create a food with different properties.
The different tiers of flour available are:
|Tier 1||Tier 2||Tier 4|
|Oatmeal|| Rye Flour
Flour inherits the purity of the Ear of Cereal it is created from, combining different batches of flour in a Barrel or Dry Goods Bag averages the purity and cannot be reversed. Mixing different types of flour results in generic "Flour" and cannot be separated.
