Starter:- Pan fried scallops with some sort of slop puree, preferably cauliflower. For extra points add a lump of black pudding.
Main:- Pan fried duck with some sort of fruit, orange, plum or redcurrants always go down well. Serve with either fondant/crushed potatoes and a red wine jus.
Pudding:- Chocolate fondant. Doesn't matter what you serve with it, if it works you will be hailed a genius regardless, if it doesn't, you will be sent home anyway.
If you want to be the wacky, 'inventive' one, add a bit of fruit to the scallops (apple maybe?), change the fruit you serve with the duck to a less conventional one (nectarine, perhaps?) and add some chilli to your chocolate fondant.
I love Masterchef but I'm so bloody sick of seeing the same dishes rehashed all the time!
