Make chicken liver mousse and add egg yolks.
Put mousse in fridge.
Make tiny square fondant potatoes with concentrated chicken stock with some vinegar. At the end add cubes of apple and some dill.
Make a really concentrated cep oil. Make tiny squares of cucumber and cover them in the salted cep oil.
Add sugar on surface of chicken liver mousse and use a gas burner to caramelize the sugar.
Let the mousse cool to room temp. Add the various cubes, sour cream and some nice green garnish like cress.
Not pretty but very delicious.
