What is praline?
Praline is a very special nut paste that is often used in patisserie. It consists of only 2 main ingredients: roasted nuts and caramelized sugar. Both are mixed until the nuts release their natural fat and the mixture becomes creamy.
Chocolate mousse cake with pears
The pear compote in the middle of the chocolate mousse is frozen in a silicone mold with a diameter of 13.7cm. Unlike fruit compote for cakes or pastries, it is important to use pectin NH as a binder for this pear filler. In contrast to cornstarch or agar-agar, this has the ability to be frozen and thawed again without losing its stability and binding and thus preventing water from escaping.
It is important to mix the pectin NH with a small amount of sugar before adding it to the other ingredients to avoid lumps. In addition, the pectin must reach a temperature of at least 80°C to be activated.
If you don't have the appropriate silicone mold, you could draw a circle with the appropriate diameter on a firm base of baking paper and place the compote inside the circle. Just make sure that the compote doesn't go too far over the edges. Then cover the surface with foil and freeze the pear filler in this way.
The rock glaze
This type of chocolate glaze consists of chocolate, vegetable oil and usually chopped nuts. The vegetable oil makes the chocolate layer a little softer, which makes it easier to cut.
The production is simple: Melt the chocolate, add the vegetable oil and stir until smooth. Finally, stir in the chopped nuts, let the glaze cool to 30-35°C and then coat the cake. In order for the icing to stick nicely to the cake, it is important that it is refrigerated (30 minutes in the fridge is enough!).
Tip: When glazing, I line a large bowl with aluminum foil, place a cooling rack on top of the bowl and place the cake on top. This allows the remaining glaze to be caught in the foil and hardened to use for the next project!
Important:
Since this chocolate mousse cake is frozen glazed and slowly thawed, condensation will occur, which will cause unsightly streaks after a while. With a flambé burner, you can carefully heat the corresponding areas on the lowest heat setting. This will give the chocolate its beautiful shine back!
How to make a vegan mousse cake -step-by-step
Step 1: Prepare the pear garnish. To do this, put the finely chopped pears in a saucepan with sugar and lemon juice and heat to 40°C. Separately, mix the pectin NH with a small amount of sugar, stir into the other ingredients and heat the mixture to 80°C, stirring constantly. Pour the compote into the silicone mold, cover with foil and freeze overnight.
Step 2: Prepare the tonka ganache: Pour warm vegan cream and the ground tonka bean over the vegan white chocolate to make a ganache. Add the cold vegan cream, mix briefly with a hand blender to combine the components. Cover the ganache with foil and place in the fridge overnight.
Step 3: For the praline, caramelize the sugar in a pan, place on a baking tray with baking paper and allow to harden completely. Break the caramel into pieces, put it in a high-speed blender together with the chopped hazelnuts and salt and mix to a fine, liquid paste. Add a little vegetable oil if necessary.
Step 4: Bake the hazelnut cake in a 24cm springform pan, let it cool completely, cut off the dome and cut out a circle with the 16cm cake ring. Place the cake ring on a board with baking paper, line with cake foil (at least 8cm wide/high, as the cake will be higher than the cake ring) and place the hazelnut cake in place. Use the back of a piping nozzle to hollow out about 13 small holes, fill them with praline and place the cake in the freezer for 30 minutes.
Step 5: Prepare the crispy layer. To do this, crumble the wafer sheets or cornflakes, melt the chocolate with the praline and mix the two until all the pieces are coated in chocolate. Spread this mixture on the hazelnut base. Put the cake ring back in the freezer.
Step 6: Make the mousse (feel free to check out this post for a detailed description) and put the first half on top of the crispy layer. Then place the pear garnish in the middle, pour in the remaining mousse, smooth the surface and freeze the entire cake overnight.
Step 7: For the rock glaze, melt the chocolate, add vegetable oil, stir until smooth. Add the hazelnuts and let the mixture cool to 30-35°C.
Step 8: Glaze the cake. To do this, line a bowl with foil to catch the excess icing. Place a wire rack on the bowl, remove the cake from the freezer, remove the cake ring and cake edge foil and place the cake on the wire rack with the mousse side down. Glaze the cake, place a piece of baking paper on the surface, place a board on top and carefully turn the cake over so that the mousse is facing up.
Step 10: Dust the ganache discreetly with cocoa powder and let the cake thaw in the refrigerator. If necessary, carefully remove the streaks from the condensation with a flambé pasture. To do this, set it on the lowest setting and carefully heat the corresponding areas.
