Make sure your food is cooked perfectly with the St Helens Home Garden thermometer. A meat thermometer accurately tells if your food is cooked or not. It also helps to prevent overcooking. To be safe, foods such as meat and poultry must be cooked to a safe minimum internal temperature to destroy any harmful organisms that may be in the food. The thermometer can also be used in beer, jam and bread making. Extremely easy to use. Insert the probe into food as it cooks and wait for the temperature reading to settle. Temperature can be displayed in deg C or deg F. The thermometer will auto-shutdown after 10 minutes.
