Cooking: Heat transfer, doneness, and food-safety temperatures

You pull chicken off the grill when it "looks done" and regret it later—colour and juice are unreliable thermometers because heat transfer from the pan edge differs from the centre. Carryover cooking keeps internal temperature rising after you remove food, so timing needs margin or a probe placed in the thickest part without bone skew.

Practical use: meal prep, hosting, and camping stoves. Edge case: sous-vide and thin cuts change probe placement rules; always cross-check official guidance. FoodSafety.gov publishes a minimum internal temperature chart [1]; the FDA Food Code portal links model retail rules for cross-jurisdiction context [2].
