What type of center appearance should a rare steak have?

The center appearance of a rare steak should be red. This is characteristic of cooking meat to a rare degree, where the internal temperature typically ranges from 120°F to 125°F (49°C to 52°C). At this temperature, the proteins in the meat have begun to coagulate, but the muscle fibers remain tender and juicy, giving the steak a bright red color in the center.

While options like pink can be indicative of medium-rare steak, and grey or brown generally hints at overcooking, the quintessential visual cue for a rare steak is that vibrant red center, reflecting how minimal cooking has occurred while still ensuring the steak is safe to consume. This distinction is important for culinary professionals to ensure they are presenting dishes that meet expectations for various degrees of doneness.
