Sweet Potato Noodle Kugel

I originally clipped this recipe from a magazine many years ago, and I've been making it ever since. Sadly, I don't think it would ever be kosher for our seder table (I've never found kosher-for-Passover egg noodles; more importantly, we eat meat at that meal, so the sour cream & butter make this dish a no-go). I sometimes make it with peach jam, since often I make more of that than apricot; it's good either way.
