Leeks are a very mellow version of an onion and when cut they have a beautiful variation in color. They go from white down by the root, to a yellow center, to a really dark green at the top. Cut the leek just below the really dark green part. Those really dark, green leaves are very tough and you donât eat them.

Inorganic chemistry, on the other hand, is the opposite.
