Put safety first when cooking meat and use a meat thermometer to check your joint is cooked through.
If you have trouble cooking rare beef or worry that your roast chicken might not be fully cooked, a meat thermometer will take away all the guesswork for you. The gauge shows the optimum temperature for the different types of meat so as long as the needle swings round to the correct temperature for the meat you are cooking, then you can be confident that it's ready to serve.
Remember to test the thickest part of the meat, away from bones for the most accurate reading. This thermometer should not be immersed in water so a good tip is to clean it with an antibacterial wipe.
