Keep in mind, however, instant-read thermometers are NOT ovenproof and can NOT be left in the meat during cooking. Instead, near the end of the cooking time, insert the thermometer into the thickest part of the food. Most models register the internal temperature in about 15 seconds. Check the stem for an indentation indicating how deep it must be inserted into the meat for an accurate temperature reading. Dial-type thermometers must penetrate approximately two inches.
Most digital thermometers read the temperature at the tip.
It is important to check the temperature of the stuffing and the meat separately. The thermometer may be inserted sideways in thin items such as patties.
