When you are cooking certain delicate items, you need to be able to ensure that the heat is being applied evenly and that the heat isn't too strong on the pan. When you are making candy, icing or other delicate delicacies, the Norpro Heat Diffuser 21cm is a great way to keep them from being ruined by too much heat. This diffuser can also be used to keep delicate containers, such as porcelain ones, from cracking from being overheated. Hand wash this diffuser to keep it clean and working well. The wooden handle will keep your hands cool as you easily control the heat distribution on your container.
