To chop onions the easy way, start by cutting off the stem end then peel the skin back to the root, keeping the skin attached. Holding the skin to steady the onion, slice through nearly to the root end then, at right angles to the first cut, make 3 or 4 more cuts nearly to the root end. Next, still holding the root end by the skin, slice finely across the onion from the stem end.

The result will be nicely chopped onion and no tears !
