Flan d'Onion

Ingredients and steps:

- 800 gr of onions, sliced. I usually use shallot because it has such a nice sweet taste.
- 60 gr butter
- 3 egg yolks
- 1 tbsp flour
- 20 cl milk
- 10 cl crème fraiche
- 1 tsp mustard (de Dijon)
- some muscat nut
- salt/ pepper
- puff pastry

Saute the onions in the butter for a few minutes. Add some water to it and let them cook till they are completely soft, about 20 minutes or so, stirring occasionally and adding water if necessary.

When ready, add the flour and mustard.

Mix the milk and crème fraiche and warm it in a pan. Add the egg yolks to it and then add the onions.

Add the salt and pepper and the muscat nut.

Place the puff pastry in a cake shape and add the onions. Bake it for 25 minutes and a pre-heated oven at 200 degrees. Serve with a nice salad.
