Chocolate lemon chou

Choux pastry is a technique that may seem mysterious and complicated, but once you have a few tricks to make it succesfully, it's a real pleasure. For this recipe, for example, I've opted for a combination of flavours by keeping more or less the traditional shape of the choux pastry and adding a decoration around it.

Being a big fan of chocolate, I wanted to add this ingredient with an extra touch: lemon. So the chou is topped with a chocolate and lemon ganache as well as a creamy lemon filling inside.

Before we start the recipe, let's go back to the basics of choux pastry. To make this dough, first bring the milk, water, salt, sugar and butter to a boil, then add the flour. First important step: make sure to dry the pastry well before removing it from the heat. Once off the heat, allow the steam to escape before adding the eggs. There are two options for doing this: you can either mix the pastry with a stand mixer, or you can mix it by hand with a spatula.

Once the steam is completely removed from the pastry, the eggs are added gradually, mixing them into the dough.

The choux pastry is ready when it is shiny and not too dense.
