Roll out the dough
to a thickness of 1/8 inch (3 mm). Prick with a
fork, turn over and line a greased tart pan with
it. Cover with baking paper and dried beans.
Bake
blind for 15 min.

Discard the paper
and beans. Brush the crust with beaten salted
egg white, so that the crust will remain firm.
Bake for another 2 min.

out.

Prepare the milk
chocolate mousse: bring to a boil 3 1/3 fl oz
(10 cl) of crème fraiche and pour over pieces of
milk chocolate. Whisk. Cool and fold in 1 1/4
cup (30 cl) of whipped cream. Refrigerate for 30
min.
-
Meanwhile prepare
the dark chocolate mousse: bring to a boil the
remaining crème fraiche and pour over the dark
chocolate, also broken into pieces. Cool. Add
the whipped cream.
-
Surround the crust
with a ring of baking paper to facilitate the
assembly of the tart. Fill the base with half of
the dark chocolate mousse.
-
Next pour the milk
chocolate mousse on top. Smooth out, using a
heated spoon. Refrigerate for 1 h. Cover with
the remaining dark chocolate mousse. Refrigerate
again for 1 h more before serving.
