How to make foundation bread
After building a wheat farm and collecting wheat, you need to build a windmill that converts the wheat into flour. A windmill can convert four units of wheat into one unit of flour, which means you need to continuously produce wheat if you want to maintain a stable bread supply.
Now that you have flour, you need to build a bakery. A bakery consumes three units of flour and one unit of water at a time to produce five pieces of bread. For water, you can build a well near the bakery, which will suffice.
You also need to distribute the bread to the granary so that the bakery workers can store the bread there. In addition, in order to feed your villagers, you have to distribute the bread to market stalls for sale so that the villagers can buy bread and meet their needs.
