Rolled oats in the context of "Steel cut oats"

The oat (Avena sativa), sometimes called the common oat, is a species of cereal grass grown for fodder and for its seed, which is known by the same name (usually in the plural). Oats appear to have been domesticated as a secondary crop, as their seeds resembled those of other cereals closely enough for them to be included by early cultivators. Oats tolerate cold winters less well than cereals such as wheat, barley, and rye, but need less summer heat and more rain, making them important in areas such as Northwest Europe that have cool, wet summers. They can tolerate low-nutrient and acid soils. Oats grow thickly and vigorously, allowing them to outcompete many weeds, and compared to other cereals are relatively free from diseases.

Oats are used for human consumption as oatmeal, including as steel cut oats or rolled oats. Global production is dominated by Canada and Russia; global trade is a small part of production, most of the grain being consumed within the producing countries. Oats are a nutrient-rich food associated with lower blood cholesterol and reduced risk of human heart disease when consumed regularly. One of the most common uses of oats is as livestock feed; the crop can also be grown as groundcover and ploughed in as a green manure.

Oatmeal is a preparation of oats that have been dehusked, steamed, and flattened, or a coarse flour 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.

Muesli (/ˈmjuːzli/ MEWZ-lee) is a cold Swiss dish that has become a common breakfast cereal prepared without cooking. Developed around 1900 by Swiss physician Maximilian Bircher-Benner for patients in his hospital, in Switzerland, it is also consumed for supper as Birchermüesli complet, 'Bircher's complete little mush', i.e., muesli with café complet (milk coffee accompanied by Butterbrot [bread, butter and jam]).

Traditionally, the primary ingredient is rolled oats which have not been processed further. The original preparation was to soak the oats in water overnight ("overnight oats") and eat the next morning with fresh apple, nuts, lemon juice, and sweetened condensed milk. Variation over time was natural: substituting other citrus juice or adding additional ingredients such as grains, seeds, and fresh and dried fruits. Yogurt, milk or other milk products, or milk substitutes are now common ingredients in both homemade and commercially packaged muesli recipes.

Granola is a food consisting of a mix of rolled oats, nuts, seeds, honey (or other sweeteners such as brown sugar), and sometimes puffed rice that is usually baked with oil until crisp, toasted and golden brown, sometimes forming clumps. The mixture is stirred while baking to avoid burning and to maintain a loose breakfast cereal consistency. Dried fruit, such as raisins and dates, and confections such as chocolate are often added.

Granola is often eaten in combination with yogurt, honey, fresh fruit (such as bananas, strawberries or blueberries), milk, or even with other forms of cereal. It also serves as a topping for various pastries, desserts or ice cream. Granola is similar to muesli, except the latter is traditionally neither sweetened nor baked.
