Chocolate Mousse Cake

At photo is relly a Biscuit Cake with Chocolate Mousse. And it can pretend to get a serious award. Ruslan packed this delicate dessert in a bag. Yes, yes, in a handbag. You open it and there is a surprise in the form of a fabulous dessert, the taste of which, just get dizzy.

And with each spoon the level of pleasure only increases, just as the smile in May. Because of first sun peeping through the window in the morning or because of this spring and fresh air. Spring ait is the most fresh and it is filled with different unique smells.

Surprise and disbelief are appeared at your face. But, do not panic. It’s simple. An easy chocolate mousse plus easy biscuit cake.

Adapted for a home kitchen by our editors from Ruslan Vychurov's restaurant recipe. Ruslan Vychurov sets milk chocolate mousse in log-shaped moulds around a line of lemon confiture and a strip of chocolate sponge spread with blueberry confiture, closes it with a strip of almond shortbread, freezes it and sprays it with green velvet. The home version builds the same log upside down in a loaf tin lined with cling film, uses jarred lemon curd and blueberry jam, cuts the gelatin to an amount that still slices cleanly, and finishes the cake with cocoa or grated chocolate instead of a velvet spray. The pastry and sponge are scaled to make one log. Not yet tested from this page.

Ingredients

Method

  1. Beat the butter with the powdered sugar until smooth.
  2. Beat in the almond flour and egg yolk, then the flour, just until a soft dough forms.
  3. Roll the dough between two sheets of baking paper to 3 mm thick and freeze it for 15 minutes.
  4. Heat the oven to 170°C (340°F).
  5. Peel off the top paper and cut a rectangle the size of the top of your loaf tin, about 22 × 12 cm; bake the trimmings as biscuits.
  6. Slide the rectangle, on its paper, onto a baking sheet and bake for 12–15 minutes, until pale golden at the edges.
  7. Let the shortbread cool on the sheet; it is fragile while warm.
  8. Turn the oven up to 180°C (350°F) and line the 20 × 30 cm tray with baking paper.
  9. Whisk the eggs with the sugar for 5–7 minutes, until thick, pale and leaving a ribbon trail when the beaters are lifted.
  10. Sift the flour and cocoa over the eggs and fold them in gently in 3 additions.
  11. Spread the batter evenly on the tray and bake for 8–10 minutes, until it springs back when pressed.
  12. Cool the sponge, then cut a strip about 20 × 9 cm, slightly narrower than the middle of your tin.
  13. Line the loaf tin with cling film, leaving plenty hanging over the sides.
  14. Soak the gelatin sheets in cold water for 5 minutes, or sprinkle powdered gelatin over 3 tbsp of cold water.
  15. Bring 200 ml of cream just to the boil and pour it over the chopped milk chocolate.
  16. Leave for 1 minute, then stir from the centre until smooth and glossy.
  17. Stir the squeezed gelatin (or the soaked powder) into the warm ganache until dissolved.
  18. Let the ganache cool to about 30–35°C (86–95°F), barely warm to the touch.
  19. Whip the 250 ml of cold cream to soft peaks.
  20. Fold the whipped cream into the ganache in two additions to make the mousse.
  21. Pour about two-thirds of the mousse into the lined tin.
  22. Spoon the lemon curd into the piping bag and pipe a line down the centre of the mousse, pushing the tip just below the surface.
  23. Spread the blueberry jam over the sponge strip.
  24. Lay the sponge jam side down on the mousse and press it in lightly.
  25. Spread the remaining mousse over the sponge and smooth the top.
  26. Lay the shortbread on top and press gently; it will become the base.
  27. Cover with the overhanging film and freeze for at least 6 hours, or overnight.
  28. Turn the cake out onto a board or serving plate, shortbread side down, and peel off the film.
  29. Dust with cocoa or scatter with grated chocolate.
  30. Refrigerate for 1–2 hours to soften before serving.
  31. Cut into 8 slices with a knife dipped in hot water and wiped dry between cuts.
What we changed for home
  • Log mould replaced with a 900 g (2 lb) loaf tin lined with cling film Special log moulds are a pastry-shop item; a loaf tin gives the same long shape, and the film lets the frozen cake slide out.
  • Gelatin in the mousse cut from 15 g to 6 g 15 g of gelatin sets 650 g of mousse rubbery; 6 g is enough for a frozen log that slices cleanly once thawed.
  • Lemon 'confiture whipped with gelatin' replaced with lemon curd piped straight in That step gives no gelatin amount and is hard to follow. Lemon curd from a jar gives the same sharp lemon line through the mousse.
  • Green velvet spray replaced with cocoa powder or grated chocolate A velvet finish needs a spray gun and melted cocoa butter sprayed onto a frozen cake. Cocoa or chocolate shavings look neat and taste the same.
  • Shortbread and sponge scaled down to fit one log The chef's quantities make enough pastry and sponge for several logs.
  • Oven times added: shortbread 12–15 minutes at 170°C (340°F), sponge 8–10 minutes at 180°C (350°F) The original gives temperatures but no times or doneness cues.
  • Cake thawed in the fridge for 1–2 hours before serving Straight from the freezer the mousse is hard; thawed, it is soft and creamy.
