Steak doneness is a measure of how cooked a steak is. There are five degrees of steak doneness: rare, medium rare, medium, medium well, and well done. Each degree of doneness corresponds to a different level of doneness. The recommended internal temperature for each degree of doneness is as follows: - Rare: 120-130°F. Rare steak is red in the center and has a cool, juicy texture. - Medium rare: 130-140°F. Medium rare steak is pink in the center and has a tender, juicy texture. - Medium: 140-150°F. Medium steak is slightly pink in the center and has a slightly firm, juicy texture. - Medium well: 150-160°F. Medium well steak is brown in the center and has a firm, dry texture. - Well done: 160°F or above. Well done steak is brown throughout and has a dry texture.
