Yes, lamb can be pink in the middle, especially when cooked to medium-rare or medium doneness. Lamb is a red meat, and its natural color can range from pale pink to deep red. When cooked to medium-rare, the internal temperature of the lamb reaches 145°F (63°C), resulting in a rosy pink center. This level of doneness allows the meat to retain its juiciness and tenderness while still being cooked through. It's important to note that lamb is safe to eat when cooked to the appropriate internal temperature, regardless of its color. The pinkness in the middle of the lamb is not an indication of undercooking but rather a result of the meat's natural pigmentation. If you prefer your lamb more well-done with no pinkness, you can cook it to a higher internal temperature, such as 160°F (71°C) for medium doneness or higher for well-done. Ultimately, the level of pinkness in the middle of the lamb is a matter of personal preference. It's always advisable to use a meat thermometer to ensure the lamb reaches the desired internal temperature for both safety and taste.
