1- Cook your beans in about 3 litres of water with the thyme, carrot, onion and bay leaf. After 45 minutes of cooking add some salt and prolong the cooking until the beans are easy to mash.
2- Start your oven at 180 degrees Celsius (356F).
3- Strain your beans and finely, mash them. Put this pure on a low heat to dry it out a little bit. Then, cool it down.
4- Add the butter in parcels, the cream and the egg yolks. Mix well. Season slightly and add the smoked duck and olives.
5- Line a baking tin with the bread crumbs and pour the bean mixture into it. Bake for 40 minutes.
When the cake is cooked allow it to set for 1 minutes before removing it from the tin. Serve warm with some tapenade or a spiced tomato sauce.
This recipe can be made in advance and frozen.
