Deletion of Mushroom sauce

Comment: As Phil points out by reference to the photo file, this is one of the classic "small sauces" of French cuisine, composed of a "mother sauce", in the case Bechamel sauce|béchamel or Velouté sauce|velouté, to which mushrooms and other ingredients are added. See the list of specific sauce article wiki-linked to Sauce, among which is Mushroom sauce. Oh yes, it needs improvement and proper references, but it's more than a |"how to" as it is. Having a main article linked to many sub-articles is common on WP and keeps the main subject article from getting too unwieldy

Comment: I wanted to try rescuing this article.  But "mushroom sauce" isn't mentioned in McGee's ''On Food And Cooking'' or Corriher's ''CookWise''. Heck, even ''Escoffier'' couldn't come up with more than three sentences, none of which are anything more than a recipe. http://books.google.com/books?id=OO7NVyLhiSYC&pg=PA35&lpg=PA35&dq=mushroom+sauce+escoffier+-wikipedia&source=bl&ots=6brxQGKP6R&sig=drREzwIELgUojr5QH0BxIF_8r7c&hl=en&ei=0X_5Te20NYjVgAfC9Pz6BA&sa=X&oi=book_result&ct=result&resnum=2&ved=0CB0Q6AEwAQ#v=onepage&q&f=false There's not really a higher authority for sauces than Escoffier. And as we know, |Wikipedia isn't a cookbook. To the extent that mushroom sauce has any notability, it should be a brief mention at Allemande sauce, because that's the mother sauce of ''Sauce aux Champignons
