We’ve all heard of Roast Beef ‘au jus’. As former resto servers and food worshipers, we (Lisa & Michael) have been asked for ‘some more au jus’. It’s a minor pet peeve that this is the improper use of the phrase. ‘Au jus’ literally means ‘with the (natural, unthickened) juice (of the meat in question)’. So in asking for more ‘au jus’, one is asking for more ‘with juice’, not ‘more juice’. So impress your friends and say “may I have more jus please”.
