Answer 1

You start by making gruel, like oatmeal. You accidently leave it too long and it gets fizzy and you get beer, more or less. Take the same stuff, draining the liquid, cause you drank the beer, and try to heat it up for dinner and you’ve got some primitive bread, depending on if you mashed up the grains.
