Gruel is a thin, watery porridge made by boiling grains, such as oats or rice, in water or milk. It is often cooked until it reaches a smooth, easily digestible consistency. Gruel has been a staple food in many cultures, especially during times of scarcity, due to its simplicity and low cost. Historically, gruel has been associated with poverty and hardship, often served to the sick or as a basic meal for the poor. Despite its humble origins, it can be nutritious and is sometimes enhanced with ingredients like fruits, honey, or spices for added flavor and sustenance.
