This apple corer (left) does two jobs in one! Not only does it remove the center of the apple containing the seeds, it also cuts the apples into slices. And the cushioned handles make it easy to push it down onto the apple.
Whenever I want to make a gluten-free snack, the apple corer is a very handy tool! They are not expensive. I paid less than $3 for mine. And it has saved me a lot of time in the kitchen.
