master-cooks | Why Smoked Meat Might Still Be Pink Inside

Smoked meat often retains a pink hue even when fully cooked due to a combination of chemical reactions and the smoking process itself. This phenomenon is primarily attributed to the interaction between the meat's myoglobin and the compounds in smoke. Myoglobin, a protein in muscle tissue responsible for transporting oxygen, gives raw meat its red color. When meat is smoked, the heat causes myoglobin to undergo a transformation, but certain conditions can stabilize its pink color. The nitrites and nitrates present in wood smoke play a significant role; they react with myoglobin to form a stable pink compound similar to the one found in cured meats. Additionally, the temperature and duration of smoking contribute to this color retention. Low and slow cooking helps maintain moisture and can preserve the pink appearance. It's important to note that the pinkness is not necessarily an indicator of undercooking. To ensure safety, using a meat thermometer is essential for checking the internal temperature, which should reach the recommended level for the specific type of meat being prepared. Understanding these factors can alleviate concerns and enhance appreciation for the unique characteristics of smoked meats.

The science of smoke rings

The mystery of that pink ring in your smoked meat can be attributed to a protein known as myoglobin. This molecule is closely related to hemoglobin, the protein you may recall from high school biology that transports oxygen in our bloodstream. Both myoglobin and hemoglobin contain a pigment called heme, which imparts the meat's characteristic blood-red hue.

Here's where it gets fascinating: Raw meat initially appears purplish, but it turns bright red when it comes into contact with air. If left out longer, it will eventually develop a rusty brown color, typical of well-done steaks. This color change can be understood by examining myoglobin's interaction with oxygen. This protein is highly reactive to oxygen—just a small amount can alter its color.

When you place the meat in a smoker and ignite the wood chips, nitrogen dioxide (NO2) binds to the myoglobin instead of oxygen. A significant amount of this gas is produced when burning wood chips like hickory in a smoker. NO2 effectively inhibits myoglobin from reacting with oxygen, which "locks in" the meat's color. Since NO2 is a gas, it cannot penetrate deeply into the meat, resulting in a pink ring around the outer layer while the interior turns a caramel brown.

Do smoked ringed meat taste better?

Smoke rings hold a nearly legendary reputation among many pitmasters, who assert that meats adorned with this ring taste significantly better than those without. The reality, however, can be both disheartening and uplifting. This reddish ring does not influence the meat's final flavor; the nitrogen dioxide responsible for it is flavorless, meaning its presence alters only the color, not the taste or texture of the meat. The smoke ring serves two primary purposes: it indicates how much NO2 bonded with the meat's surface before it was fully cooked, and it confirms that the meat was indeed prepared in a smoker rather than on another type of grill.

Additionally, it serves as a reminder that we shouldn't rely solely on visual cues to determine if meat is fully cooked. Always use a meat thermometer to ensure that smoked meat is ready to serve, as color alone may not be a reliable indicator.

If you've been having difficulty achieving a smoke ring at home, don’t worry. What will truly impress your guests is mastering the cooking time and serving those smoked beef plate ribs with a delicious marinade. And while a smoke ring can certainly spark some interesting conversation, it’s the flavor and tenderness that will leave a lasting impression.
