Anyplace to get them in Brooklyn? Boro Park?
The best way to improvise is with fresh-made jelly doughnuts from "7th Avenue Donut" near 9th Street in Park Slope...and get the BLUEBERRY jelly version...they rock!

For eating in: Mile End had both latkes and sufganiyot during Chanukah last year. I'm sure they will repeat.
