You can use many different kinds of fruits, vegetables and hard cheeses with the blade discs. The discs are ideal for slicing or shredding fruits and vegetables like cucumbers, carrots, baby potatoes, zucchini, apples and more. Make sure that ingredients are cut so they fit easily into the feed chute so that food does not get lodged or stuck while processing. If food does become lodged in the feed chute, always use the food pusher provided, or another piece of fruit or vegetable to push it down. Never insert your fingers or use any kitchen utensil to push food into the feed chute.
