Tarte au Chocolat (Metric Measurements)

Happy Thanksgiving to my American readers!

During the holiday season, we love to indulge; and there is nothing more indulgent than this French style chocolate tart, or tarte au chocolat. I've made a chocolate fudge tart in the past, which is an American style sticky sweet treat. But if you'd prefer the darker, more intense European experience of a dark chocolate baked ganache, this is for you!

I like to decorate mine with frozen berries for that frosty, wintry look. However, this can also be dusted with cinnamon or pumpkin pie spice for that quintessential Thanksgiving flavour.

INGREDIMENTS

Pastry

180 grammes plain flour

120 grammes unsalted butter (or a mix of butter and margarine), soft

20 grammes icing sugar

Optional: a beaten egg

Filling

250 grammes plain chocolate, 50 to 60% cocoa

200 millilitres whole milk

50 millilitres evaporated milk, or double cream

25 grammes butter

1 medium egg, roughly 55 grammes
Frozen or fresh raspberries, to decorate

METHOD

First, bake the pastry

• Preheat the oven to 180C, and make sure the shelf is in the middle
• Make a crumbly shortbread by rubbing all the pastry ingredients together in a mixing bowl. Press the crumbly mixture into a 25 centimetre round tart tin. Keep the pastry case thin, about 2 or 3 millilitres thick, so if there is leftover dough you can make it into a biscuit or something.
• Dock the pastry all over with a fork, bottom and sides, to make sure the pastry doesn't bubble.
• Line the pastry with foil or baking paper and fill with pastry weights, like dried beans or coins. Bake for 15 minutes, then remove the lining and cook for a further 10 minutes.
• If there are any dock holes in the pastry case that go through the bottom after baking, brush the pastry case with the beaten egg and pop back in the oven for about a minute.
• Allow the case to cool completely before filling.

Then, make the filling

• Preheat the oven to 150C. Break the chocolate up in a heatproof bowl. 
• In a saucepan heat the milk, evaporated milk (or cream), and butter to boiling point. Pour the hot milk mix over the chocolate and leave to stand for 3 minutes. 
• Whisk the chocolate mix until completely smooth. In a small bowl, beat the egg and add in a small amount of the hot chocolate mixture, whisking all the time. This tempers the egg so that it won't scramble.
• Add the egg back into the main chocolate mixture and stir well. Pour the filling into the case through a strainer to remove most of the bubbles. If there are any big bubbles on the surface after a gently wiggle, pop them with the corner of a piece of kitchen paper.
• Bake for 20 to 25 minutes. When ready, it should have a skin over the whole surface and have a gentle wiggle under the surface.
• Allow to cool completely before putting in the fridge for at least 4 hours to chill thoroughly.
• Before serving, allow to come to room temperature. This tart is best served with whipped cream and sour berries like raspberries, cherries, or blackberries.
