Yom Kippur is the only Jewish Holiday without food, so instead of cooking, get yourself ready spiritually.
Hat tip: Carl, also for this introduction:
This ought to get you in the mood for Yom Kippur....
It's the prayer of U'Nesane Tokef (And we will give effect to the day's sanctity) with an emphasis on the second half (on Rosh HaShanna it will be inscribed and on Yom Kippur it will be sealed) and some events that happened in the last year.
And now for a favorite of mine, the Leonard Cohen version, "Who by Fire." This one includes a very shofar-like saxophone solo.
I'll end with Dudu Fisher who performed on Broadway, but never on a Shabbat, and then returned home to Israel, nothing like The Jazz Singer. My grandchildren love his Jewish-themed DVD's and know all the words.
