Calibrating A Food Thermometer

When you use a food thermometer you need to make sure the temperature it gives you is accurate. An easy way to do this is to use ice and water.
Pack a large cup to the top with crushed ice. Put the thermometer at least 2 inches into the water. After 30 seconds, read the dial. It should read 32oF (0oC).
If it does not read 32oF(0oC) after you have waited at least 30 seconds, you need to:
1. Leave it in the ice water
2. Use pliers or a wrench and turn the nut on the back of the thermometer until the needle reads 32oF(0oC). (Add ice as it melts.)
3. Wait 30 seconds. Keep repeating these steps until the thermometer reads 32oF(0oC).
