You might not yet have a quern, but that doesn't mean you can't enjoy some lovely grain products!
Tier 0
Some grains can be hammered on a Primitive Anvil into Crushed Grains. These yield some grain nutrients themselves, but are best processed further before eaten.
Tier 0
One way to further process crushed grains is to pound them, also on an Anvil, into Coarse Flour.
Tier 0
Maize and Rice Grains are already in small pieces, so they can be pounded directly into Coarse Flour.
3
Coarse Flour can be crafted into dough, just as regular flour can, but this only yields one dough for every two flour, rather than two for every one flour.
Item: bsa:food/porridge
A more efficient option is porridge, which is made by boiling 3-5 crushed grains and 0-2 fruit in a water pot.
All Crushed Grain and Coarse Flour items can also be ground in the quern to produce regular flour.
