6: Then add beaten eggs to the chocolate mixture, and mix well.
7: Pour the mixture into the pastry case.
8: Cook about 15 minutes, watching carefully. The tart should still be the "trembling" slightly in the centre to be perfect.
9: Remove from the oven and leave to cool on a rack (careful - it's very very fragile). Serve warm or cold the same day, while the pastry is still crisp and the chocolate creamy, a pure delight!
10: For a professional look which eliminates small imperfections from the surface (like in the photograph), remember to pour the mixture into the tart through a very fine strainer.
Remarks
To decorate, you can sprinkle it, when cold, with a little cocoa powder, icing sugar and/or chocolate chips. You can also add a delicious citrus fruit flavour to the chocolate, by adding a fine layer of candied grapefruit peel before pouring in the chocolate.
