Scottish oats refer to a specific type of whole grain oatmeal produced by stone grinding the oat groats into a coarse meal of varying sizes, traditionally used to make a creamy porridge. The “200 g” refers to the weight or package size of the product, as it is commonly sold in this quantity by various brands. 

Characteristics of Scottish Oats
Processing: Unlike rolled oats (which are steamed and flattened into flakes) or steel-cut oats (which are cut into uniform pieces with a steel blade), Scottish oats are slowly ground between two large millstones.
Texture and Consistency: This grinding process creates a meal with a mix of fine and coarse particles, which results in a distinctively smooth, thick, and creamy texture when cooked into porridge.
Flavor: They are known for a rich, nutty, and naturally sweet flavor.
Cooking Time: Scottish oats generally cook faster than whole oat groats or steel-cut oats (around 10-15 minutes on the stovetop) but take longer than quick or instant oats.
Nutritional Value: They are a whole-grain food, retaining the germ, oil, and fiber of the oat kernel. They are a rich source of fiber (specifically beta-glucan, which helps lower cholesterol), protein, vitamins, and minerals. 

Common Uses
Scottish oats are a versatile ingredient and can be used in numerous ways:
Porridge (Oatmeal): This is the traditional use, typically prepared with water and a pinch of salt. Milk, fruits, nuts, or honey can also be added for flavor.
Baking: They can be incorporated into recipes for oatcakes, bread, cereal bars, pancakes, and cookies.
Other Dishes: They can be used as a wholesome addition to protein shakes, stews, or even savory dishes like risotto or curries.
