The Benriner Jumbo mandoline is a handy tool to have in your kitchen. It’s not a necessary tool but if you want to be able to slice large vegetables into thin to thick slices easily then this is the tool for you. We use this tool to make our potato chips, to slice zucchini for “lasagna”, and eggplant for the eggplant “parmesan.” You can always use a knife for these recipes but we have found that the mandoline makes the work so much easier. Especially for the chips.
