Bread is one of our oldest foods, a pillar of civilisation. Nearly every civilisation around the world has developed it. Bread has several key ingredients: (flour, liquid, oils*, leavening substance*, salt*, sugars*)

the major types for each of these are:

flours: wheat corn nut rice

liquids: water milk broth blood (yes blood)

oils: butter olive oil sesame seed oil other oils**

leavening substances: Yeast baking powder fermented stuff***

sugars: cane corn syrup maple others ****

* not essential
** too many to list, but the big distinction is between fat and vegetable oils
*** wheat flours have natural rising qualities
**** can’t list off the top of my head ...
