Coffee-Caramel Millefeuille

For the puff pastry, mix all the ingredients together for 2 minutes slow and 2 minutes fast. Let the dough rest for 10 minutes in the fridge. Roll the St-Villepré plate to 10 mm thick and give the dough 2 double foldings. Let the dough rest for 10 minutes in the fridge and give the dough again 2 double foldings. Let the dough rest for 12 hours in the fridge and roll the dough to 2 mm with a length off 35 cm on the side. Place the dough on 40x60 cm plates and let the sheets rest for 1 hour. Put a baking paper and baking tray on top before baking and bake for 25 minutes at 200°C. Once baked, sprinkle some icing sugar on top and let it melt by putting it back in the oven. Repeat this operation for the other side.  

To prepare the coffee-caramel ganache, heat up the milk with the coffee beans and let infuse for 15 minutes. Pour the milk in a sieve to separate it from the coffee beans. Heat up the coffee milk with half off the cream. Pour it on the caramel flavored milk chocolate and mix with an immersion blender. Add the rest of the cream and let it cool down for 12 hours in the fridge.

To assemble the millefeuille, cut the baked puff pastry in 4 cm wide lanes. Whip the coffee-caramel ganache and pipe it on top. Place another puff pastry sheet on the ganache. Pipe again some whipped ganache and place the last sheet off puff pastry on top. Cut portions off 10 cm wide with a sharp chef knife. Place the millefeuille on its side for better cutting. Place the assembled millefeuille with the cutted side on a carton. Finish as desired.
