Thermometer Accuracy
Source of Recipe
?
To test thermometer (meat, candy, instant-read) for accuracy, emerge at least 2 inches into a pot of boiling water. If the thermometer reads 212�, it is accurate.
If it rises above 212�F or does not reach 212�, add or subtract the difference to the temperature called for in the recipe you are making. Some thermometers have "test" marks on them at 212�F. Some thermometers, especially the "instant-red" type, have a recalibration or adjustment nut under the dial. Turn the nut if necessary to adjust.
NOTE: water boils at a lower temp at higher altitudes, for example, 202�F at 5,000 ft.
"POP-UP" thermometers are reliable to within 1-2�F if accurately placed in the product. The pop-up temp. device indicates that the food has reached the FINAL temp. for safety & doneness. It is also suggested that the temp. be checked with a conventional thermometer in several places.
