What each ingredient does

Flour
Long boiling dries and sets the flour into a firm ball, which is then scraped out to form the base of the gruel.

The step that matters

Boiling the flour bag for 3 hours. The flour must stay submerged and boil the full time so its starch is fully cooked and the ball holds together. Under-boiling leaves raw, pasty flour, and letting the bag boil dry can scorch it.
