Every cook wants thin, evenly sliced veggies for salads and cooking. A mandoline can a bit dangerous and pricey. An alternative is a box grater. Most of us have this. It has different sized blades on all sides. Cut the end off your cucumber and insert a fork. Run it down the wide slicing blade and you’ll have even slices instantly. Be sure to use the fork as a holder and hold the handle to keep your fingers safely away from the blade.
