Fat rendered from beef carcasses is known as which of the following?

The correct term for fat rendered from beef carcasses is tallow. Tallow is a type of animal fat that is primarily derived from cattle but can also come from sheep. It is utilized in various applications, including cooking, soap making, and as a lubricant.

Understanding the other options helps clarify why they are not the correct answer. Lard specifically refers to rendered fat from pigs, distinguishing it from tallow. Suet is the firm fat surrounding the kidneys of cattle and sheep, rather than fat rendered from the entire carcass. Butterfat, on the other hand, is the fat component found in milk and dairy products, which also differs significantly from the fat rendered from beef. Thus, tallow is the appropriate term for fats derived from beef, making it the correct choice.
