Cheese changes texture when it goes from melted back to firm. But there are still plenty of ways to use it. You can chop or tear the leftover cheese and use it as a pizza topping. Or melt it again and add it to a soup for a delicious cheese flavor (I can recommend making a broccoli cheese soup or cauliflower cheese soup. Yum). Alternatively, you can make a creamy Camembert gravy with the leftovers. Just add the cheese to your favorite gravy and make sure it melts completely.
