No, I can't find it
Yeah, they don't put their recipes on the interweb much, I'll try and remember it:
2 medium onions, halved and thinly sliced
Pinch of sugar
55g butter
350g macaroni
50g flour
1.5 pints of milk
1/2 tsp cayenne pepper
salt and pepper
250g cheese
55ml double cream
100g breadcrumbs
Preheat oven to Gas Mark 6 or whatever it is in electrics.
Melt 15g butter in a frying pan. Add the onions and the sugar and fry for 20 or 30 mins, until they caramelize, then set aside.
Boil the macaroni for 8 or 9 minutes.
Melt the rest of the butter, add the flour and cayenne pepper and cook on the lowest heat for 4 minutes.
Remove from the heat and add the milk gradually, stirring/whisking as usual for a bechemel sauce.
Return to the heat, bring to boil and then immediately drop it to the lowest setting and cook for 10 minutes, stirring occasionally.
Stir in 2/3 of the cheese and the season, then mix in the pasta.
Spoon 1/3 of the pasta mixture into a dish, then add a layer of caremelized onions and top with a little grated cheese. Repeat once, then add the rest of the pasta mixture on top.
Mix the bread crumbs with the rest of the cheese and sprinkle over the top.
Chuck it in the oven for about half an hour under the top is golden.
Stuff face.
