For the /ck/ denizens that aren't sundae ramen/bacon mat spergs, what is that "one dish" for you?

You know, the one that you dream of making?
Something to impress your friends/wife?
A challenge undertaken to exhibit your mastery of the culinary arts for all the world to see?

For me, it is crown rack of lamb. Discuss your dream dishes and see if you can help anyone else.
