Final answer:
When you see juices coming out of a patty, it indicates that the patty is done. This is a result of proteins denaturing and shrinking, causing the release of juices. Use a meat thermometer to ensure the internal temperature reaches a safe level for consumption.
Step-by-step explanation:
When you see juices coming out of a patty, it indicates that the patty is done. This usually happens when cooking meat, such as a burger, where the juices released are a sign of the internal temperature reaching a safe level for consumption.
The principle behind this is that as the meat cooks, the proteins in the patty denature and shrink, causing the juices to be released. By observing the color and consistency of the juices, you can determine if the patty is cooked to your desired level of doneness.
It is important to note that the only way to accurately determine if a patty is fully cooked and safe to eat is by using a meat thermometer. The internal temperature should reach 160°F (71°C) for ground meats.
