It went brilliantly! As it turned out, not only did my parents and my little sister come for dinner, but so did my girlfriend's mother. It was quite a do.
I knocked up some sushi for starters - including Salmon, Tuna, Turbot and Amber Jack, but then I also experimented a little and created a Hoi Sin Duck sushi roll. Probably blasphemous to anyone immersed in either Chinese or Japanese culture, but I invoked the twin excuses of 'fusion cuisine' and 'it's delicious'. It was delicious, by the way.
Then my girlfriend had rustled up a fantastic lamb casserole with aubergine (mmmmm) and North African flavours. It was so tender the meat jumped off the bone.
Finally, I delivered on my promise of a chocolate-brownie-whisky cake (very simple, very rich - especially with the amount of whisky I poured over it). I think it was rescued by my girlfriend's addition of creme fraiche and poached pears.
Well, the folks went away happy anyway.
It's funny how much energy you can put into preparing dinner when you're meant to be writing a novel.
