Compare the texture of the meat to the firmness of the muscle at the base of the thumb of your completely relaxed hand. If they feel the same, the steak is:
- blue-rare
- rare.
For medium-rare, touch the tip of the index finger to the tip of the thumb of the same hand. Feel the firmness of the muscle at the base of the thumb. Check the meat to see if it is the same firmness. If it is, the steak is medium-rare.
For medium, press the tip of the middle finger against the thumb of the same hand and feel the muscle at the base. That is what a medium steak will feel like.
For medium-well, use the ring finger, and
For well-done use the pinky, as above.

well done 熟透
medium 一般(半熟）
steak 半生
