People are just learning that the red juice in rare steak isn’t actually blood. This revelation has taken social media by storm, with many people expressing shock and surprise at this unexpected discovery.
But what exactly is this pinkish-red liquid that oozes out of steaks, especially when they are cooked rare? And why does it appear so similar to blood? Let’s dive in and uncover the surprising truth.
During the slaughtering process, virtually all of the animal’s blood is drained out. This means that even the freshest steaks contain very little actual blood. So that reddish liquid you see is not what you think it is.
The liquid you’re seeing is actually called “purge” – it’s a mixture of water and myoglobin that leaks out of the meat. Myoglobin is a protein found in muscle tissue that gives meat its red color.
Purge occurs when the meat has been frozen and then thawed. The ice crystals that form during freezing can actually cut the meat cells, causing the water and myoglobin to leak out. This is why you often see an absorbent pad at the bottom of steak packaging – it’s there to soak up the purge.
Interestingly, the purge from beef tends to look more “bloody” than the purge from pork. This is because older animals, like cows, tend to have more muscle tissue and therefore more myoglobin. Pigs, on the other hand, are usually harvested at a younger age.
Bearded Butchers explains that excessive purge means the meat has lost flavor and tenderness. The more purge, the less moisture in the meat, and the less tasty it will be. This is why it’s important to let cooked meat rest – it allows the juices to reabsorb back into the meat.
As the steak is cooked, the myoglobin will darken as it’s exposed to heat and the meat loses moisture. This is why a rare steak looks “bloody” and a well-done steak takes on a grayer color.
So, the next time you see that reddish liquid oozing out of your rare steak, don’t be fooled – it’s not blood, it’s simply purge. Understanding the science behind this phenomenon can help you appreciate your steak even more, and ensure you’re getting the most flavorful and tender bites possible.
