of hulled oat grains ( groats) that have either been milled (ground), rolled, or steel-cut. Ground oats are also called white oats. Steel-cut oats are known as coarse oatmeal, Irish oatmeal, or pinhead oats. Rolled oats were traditionally thick old-fashioned oats, but they can be made thinner or smaller and may be categorized as quick oatmeal or instant oatmeal depending on the cooking time required, which is determined by the size of the oats and the amount of precooking.


Industrial preparation and varieties

The oat grains are dehusked by impact, and are then heated and cooled to stabilize the groats, the seed inside the husk. The groats may be milled to produce fine, medium, or coarse oatmeal. Rolled oats are oats that have been steamed, flattened by a "flaking roller", and dried. Old-fashioned rolled oats are made from whole oat groats and may be thick and require longer cooking time. Quick-cooking rolled oats are made from steel-cut oats and rolled somewhat thinner. Instant oatmeal is made from more finely cut oats and rolled even thinner, often with a sweetener and flavorings added.


Food uses

, or cooked with water or milk to make porridge. In some countries, rolled oats are eaten raw or toasted with milk and sugar, sometimes with raisins added, as in muesli. The term ''oatmeal'' sometimes refers to a porridge made from the bran or fibrous husk as well as from the kernel or groat. Rolled oats are often used as a key ingredient in granola, in which toasted oats are blended with sugar and/or nuts and raisins, and in granola bars. Rolled oats are also used as an ingredient in oatmeal cookies, oatcakes, British flapjack bars, and baked oatmeal dessert dishes such as apple Brown Betty and apple crisp. Oats may also be added to foods as an accent, as in the topping on many oat bran breads and as the coating on Caboc cheese. Oatmeal is also used as a thickening agent in savory Arabic or Egyptian meat-and-vegetable soups, and sometimes as a way of adding relatively low-cost fibre and nutritional content to meatloaf.

to the country's low temperatures and high humidity. As a result, oats became the staple grain of Scotland. The ancient universities of Scotland had a holiday called Meal Monday to permit students to return to their farms and collect more oats for food. Samuel Johnson referred, disparagingly, to this in his dictionary definition for oats: "A grain, which in England is generally given to horses, but in Scotland supports the people." His biographer, James Boswell, noted that Lord Elibank was said by Sir Walter Scott to have retorted, "Yes, and where else will you see such horses and such men?" In Scotland, oatmeal is created by grinding oats into a coarse powder. It may be ground fine, medium, or coarse, or rolled, or the groats may be chopped in two or three pieces to make what is described as pinhead oatmeal. Ground oatmeal, rolled oats, and pinhead oatmeal are all used throughout Britain; one Scots manufacturer describes varieties as "Scottish Porridge Oats" (rolled), "Scottish Oatmeal" (medium ground), and "Pinhead Oatmeal". The main uses are: * Traditional porridge * Brose: a thick mixture made with uncooked oatmeal (or medium oatmeal that has been dry toasted by stirring it around in a dry pot over heat until it turns a slightly darker shade and emits a sweet, nutty fragrance) and then adding butter or cream. Quick-cooking rolled oats (distinct from "instant" variations) are often used for this purpose nowadays because they are quicker to prepare. * Gruel, made by mixing oatmeal with cold water that is strained and heated for the benefit of infants and people recovering from illness. * as an ingredient in baking * in the manufacture of bannocks or oatcakes * as a stuffing for poultry * as a coating for Caboc cheese * as the main ingredient of the Scottish dish skirlie, or its chip-shop counterpart, the deep-fried thickly-battered mealy pudding * mixed with sheep's blood, salt, and pepper to make Highland black pudding (). * mixed with fat, water, onions, and seasoning, and boiled in a sheep's intestine to make '','' Outer Hebridean white pudding, served sliced with fried eggs at breakfast.

Staffordshire

Staffordshire oatcakes are a local component of the full English breakfast. It is a plate-sized pancake, made with medium oatmeal and wheatmeal (flour), along with yeast. Once the mixture has risen, it is ladled onto a griddle or bakestone and dried through. Staffordshire oatcakes are commonly paired with bacon, sausages, mushrooms, kidney, and baked beans, among others. A related oatcake is sometimes found in neighbouring Derbyshire.
