We include doneness temperatures in many of our recipes, such as those for poultry, meat, and bread. We recommend an instant-read thermometer for the job. For temperatures not represented in the chart above, use this simple formula:

Subtract 32 degrees from the Fahrenheit reading, then divide the result by 1.8 to find the Celsius reading.

EXAMPLE:

“Roast until the juice runs clear when the chicken is cut with a paring knife or the thickest part of the breast registers 160 degrees on an instant-read thermometer.” To convert:

160˚ F - 32 = 128˚

128˚ ÷ 1.8 = 71˚ C (rounded down from 71.11)
