Mandolines
Why use a mandoline when we have knives? Well, the answer is ... consistency!
A mandoline is the most useful and dangerous non-knife tool you can have in the kitchen. Its sole purpose is to uniformly cut vegetables. it's perfect if you want to create same-sized foods for uniform cooking - if all the food is the same size, it will cook at the same rate - or you may want the food to have a uniform look for display on a table or plate.
