Apple corer

It may also be used for similar fruits, such as pears or quince.

[1] An apple corer is often used when the apple needs to be kept whole, for example, when making baked apples,[2][better source needed] or when a large number of apples need to be cored and sliced, for example, when making an apple pie or similar dessert.

[3] Some apple corers consist of a handle with a circular cutting device at the end.

When pushed through the apple, it removes the core to the diameter of the circular cutting device.

The core can then be removed from the apple corer.
