How did ancient Romans make porridge?

Ancient Romans made porridge, known as "puls," primarily from spelt or barley flour mixed with water. They would cook the mixture over a fire until it thickened, often adding ingredients like vegetables, herbs, or sometimes meat for flavor. Puls was a staple food for both the lower and middle classes, valued for its simplicity and nutritional content. It was typically consumed as a breakfast dish or as a side with other meals.
