Color Lies. A Thermometer Doesn't.
Judging meat doneness by how pink it looks or how firm it feels takes years to get reliable, and even then it can mislead you: ground beef can turn brown well before it's hit a temperature high enough to kill harmful bacteria, and a chicken breast can look done on the outside while still being raw at the thickest point. An instant-read thermometer removes the guesswork entirely — probe the thickest part without touching bone, and you get a real number instead of a guess. It's the only method food safety agencies consider reliable for confirming meat has reached a safe internal temperature.
