Preheat oven to 350 degrees. Butter a 9-by-3-inch springform pan. Whip the soft butter and brown sugar until pale and smooth at medium speed, about 3 minutes. Add egg yolks, one at a time, beating well after each addition and scraping the bottom and sides of your bowl if necessary. Add the melted chocolate, vanilla extract, and salt. Beat until combined. In a medium bowl beat the 6 egg whites on high speed until soft peaks form, about 2 minutes. Very gently fold one-third of the egg whites into chocolate mixture. Fold in remaining egg whites and pour batter into prepared pan, and bake 25 minutes. Meanwhile prepare the merengue. Beat remaining 4 egg whites on high speed until frothy. With the mixer running, slowly add the sugar and continue beating until stiff peaks form, about 8 minutes. Remove cake from oven. Using a spatula spread meringue mixture on top of cake, sprinkle with chopped pecans. Bake until meringue is lightly browned for 10 minutes. Then lower the temperature to 300 F and bake 10 more minutes. Meringue should become golden, but still soft, airy and weightless. Transfer the pan to a wire rack; let stand 10 minutes. Run a knife around the edge of the cake to loosen, and release sides of the pan. Let cool, about 30 minutes, before slicing and serving

To make a beurre noisette, you need to melt the butter in a small sauce pan. Boil until it becomes light brown. Pour into a bowl and let cool. Place sugar and water in a pan. Simmer until the sugar dissolves, stirring contininuously. Bring to a boil, turn off after about 1 minute. Add the raisins to the hot syrup and leave to cool. Preheat oven to 400 F. Beat the egg whites until they start to foam, but still are not whipped. Continuing to whisk, gradually add sugar. Beat until thick and creamy. Add the sifted flour and ground almonds, beat for a short time just to mix, add the cooled beurre noisette . Derain the raisins and add to mixture. Spoon the mixture into molds for financiers 3 x 1 1/4 x 1 1/4. Bake for 20 minutes. Then remove from oven and place on a wire rack to cool. Mix all the ingredients for the deep. I will tell you one trick - for the perfect moisturising, you need to pour the liquid into a spray. The process became much easier. Spray financiers, while they are still hot.
