First I mixed all the dough ingredients and mixed it with his hand.
Then I fried the bacon in olive oil, put the onion, leek, broth and
white wine. I left as did butter the pan and open the way to mass. Then
I threw the onions on top and took it to the oven for 20 minutes.
Meanwhile, mix all the ingredients of flan (There is a thinning thinning a bit of nutmeg, which has a special flavor).
I took the mass of the oven after the season, and threw the custard on
top. Baked for another 20 minutes or so and was ready and super tasty.
