What type of solid forms when cooking grease solidifies?

When cooking grease or oil solidifies, it forms a type of solid known as a 'fatty solid' or a 'food solid'. These solids primarily consist of saturated fats, which are commonly found in animal-based products and some vegetable oils. When these fats cool down and solidify, they form a semi-solid or solid state. The exact texture of the solidified grease or oil depends on various factors, such as the type of fat present, the temperature at which it solidifies, and the presence of other components in the mixture.
