Gruel is a food consisting of some type of cereal—such as ground oats, wheat, rye, or rice—heated or boiled in water or milk. It is a thinner version of porridge that may be more often drunk rather than eaten. Historically, gruel has been a staple of the Western diet, especially for peasants. Gruel may also be made from millet, hemp, barley, or, in hard times, from chestnut flour or even the less bitter acorns of some oaks. Gruel has historically been associated with feeding the sick and recently-weaned children.

Wheat is a grass widely cultivated for its seed, a cereal grain that is a worldwide staple food. The many species of wheat together make up the genus Triticum ; the most widely grown is common wheat. The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BC. Botanically, the wheat kernel is a caryopsis, a type of fruit.
