Nigella's Marmalade Pudding Cake

Having said last week that although I make marmalade every year, I don't really eat the stuff except in puddings, I thought I'd better make one.  This is quite simple - a rich sponge flavoured with fresh orange zest and juice and quite a lot of marmalade, and glazed with more of the stuff when it comes out of the oven.  I halved the recipe, otherwise we'd be eating it forever.  Perfect Sunday Dinner fodder!  The recipe can be found on Nigella's site, so I link to it here.  Whilst I'm at it, I've pinched her picture!  Mine rose a little more in the middle, but I don't think that affected the taste.
