Scottish porridge is traditionally made from oats.
Porridge is a hot cereal prepared by boiling grains or other starchy plants in water or milk. In Scotland, oats became especially important because they grow reliably in the country's cool, wet climate. Scottish porridge is commonly seasoned with salt, although sugar, honey, fruit, or cream may be added.
The word “porridge” describes a preparation rather than one single grain. Oat porridge is the best-known Scottish version, while other cultures make porridge from rice, maize, millet, barley, or wheat. Steel-cut, rolled, and ground oats can all produce porridge with different textures.
Oatmeal and porridge are closely related terms, but regional usage differs. In North America, “oatmeal” usually means cooked oats; in Britain and Ireland, “porridge” is the more common everyday term for the dish.
