Well, this feature request has been issued before. I cannot find a definate official statement though.
Provide a browseable index for http://www.chow.com/ingredients/
So far you can only navigate through it by means of hacks (direct url entry with increasing ids, linked from recipes, search results ...). An automated index with alphabetical sorting should be easy to realize, yet will be very handy.
So would you PUUULLEEEASSSSSEEEE give us that feature? ;(
