What You Need to Know
Rendering involves the breakdown of triglycerides in animal fat through heat, resulting in the separation of fat and impurities. This process typically occurs between 160°F to 190°F (71°C to 88°C) for several hours, and failure to control temperature can lead to the formation of off-flavors and oxidation.
