How Should You Cut An Onion?
To cut an onion, first, cut off the root end and the top. Next, cut the onion in half lengthwise, peel off the outer layer, and slice each half lengthwise. Finally, chop the sliced onion perpendicular to the cuts made earlier to achieve either diced or minced onions. It is also important to use a sharp knife to make clean cuts and avoid crushing the onion, which can release more of the pungent odor.
