This recipe came from my friend Myra’s mum in Ireland and is truly yummy!
2oz butter
8oz leeks
1/4 pint stock
1/4 pint milk
1/2oz flour
1/4 pint cream
2 egg yolks
3oz cheese (grated)
salt + pepper
Make flan case using 6oz flour (3oz brown/ 3oz white) and 3oz fat. Chill pastry in fridge for 15 minutes before baking. Part bake for 10 minutes.
Melt butter and fry leeks for 2 minutes. Add stock, cover and simmer for 10 minutes. Drain leeks and make liquid up to 1/4 pint with milk. Make a roux with a little butter and flour and add liquid stirring until creamy. Beat egg yolks and cream and add to sauce OFF THE HEAT. Stir until thick and creamy (do not boil). Add 1/2 grated cheese. Spread leek on flan base. Pour sauce over and sprinkle with grated cheese.
Bake at 375F for 25 minutes.
It can also be made without the egg yolks and with greek style yoghurt instead of the cream - and that works out nice too!
