Both options are Knot Kwite Kosher, but ... with Chanukah coming up, and the simple fact that everything fried somehow tastes to much better ... I present my favourites in London.
The doughnuts I love are from my favourite little Polish sklep: Prima. These Pączki are fabulous, and available fresh daily.

And the Cannoli that Don Lobel likes to be given?
Those come from Casa Cannoli, and are freshly piped – at the Duke of York Square Market on Saturdays, and various other places in London, see: Casa Cannoli. They also cater, so if you are planning a Chanukah party ... book 'em before someone else does.
