Whether you want to pit your fruit to freeze it or you are using the cherries in a recipe, it's a good idea to know the right way to remove the pits. Invest in a cherry pitter, which is a gadget that pushes the pit through the fruit and out the other side. This is definitely the easiest way to get rid of the pits. At a pinch, you can use a sharp knife to cut around the pit and take it out but that takes longer and is more fiddly, so your best option is to get a cherry pitter if you often need to pit cherries.
