What recipe are you extremely eager for but have never found the "exact" one?

I think we all have a dish in the back of our mind that we have spent years wishing we could experience again, but somehow the essence of it eludes us.

My great grandmother made the best spinach souffle. She made this hundreds of times for us all over the years and now no one remembers anything about how to make it. Whenever I prepare a spinach souffle from a highly rated cook book, it still tastes like something is missing.
