Chestnut And Whiskey Mousse With Chocolate And Walnut Biscuit And Chocolate Sauce Recipes

Steps:

• Bring chestnuts, milk, and salt to a simmer in a medium saucepan over medium heat. Partially cover; cook until chestnuts are very soft and milk is reduced to 1/4 cup, about 15 minutes. Process mixture in a food processor until very smooth (if needed, add more milk, 1 tablespoon at a time).
• Pass through a fine sieve into a bowl; discard solids. Press plastic wrap directly onto surface. Refrigerate puree 1 hour.
• Stir together sugar and 1/3 cup water in a small saucepan until sugar is dissolved. Bring to a boil over medium-high heat; cook until syrup registers 238 degrees on a candy thermometer (carefully tilt pan to fully submerge thermometer tip).
• Meanwhile, put yolks in the bowl of an electric mixer fitted with the whisk attachment. With mixer running on low speed, gradually pour syrup down side of bowl. Increase speed to high; beat until pale, fluffy, and cool, about 8 minutes.
• Whisk cream in a clean mixing bowl until soft peaks form; set aside.
• Stir egg mixture into puree; whisk until smooth. Gently fold in whipped cream. Chill, with plastic wrap directly on surface, at least 2 hours or overnight.

Steps:

• Whip 1 cup of the heavy cream to soft peaks in a medium bowl (see Cook's Note). Set aside.
• Add the egg, egg yolks, sugar, espresso powder, vanilla extract, salt and 1 tablespoon water to a medium heatproof bowl and whisk to combine. Set the bowl over a medium saucepan of gently simmering water (do not allow the bowl to touch the water). Whisk constantly until the mixture is pale, hot to the touch and has almost doubled in volume, about 4 to 6 minutes, scraping down the sides of the bowl occasionally with a rubber spatula, if necessary. Remove from the heat and continue whisking until cooled, about 2 minutes.
• Put the chopped chocolate in a medium heatproof bowl and set over the saucepan of gently simmering water (do not allow the bowl to touch the water). Stir occasionally with a rubber spatula until the chocolate is melted and smooth. Remove from the heat and gently stir for about 3 minutes to cool slightly.
• Whisk the egg mixture into the melted chocolate in 3 additions until combined. (The mixture may get very thick.) Using a rubber spatula, gently fold the whipped cream into the chocolate mixture in 3 additions until it is fully incorporated. It is important that the chocolate mixture is not warm to ensure that it combines smoothly with the whipped cream without seizing up.
• Divide the chocolate mousse among four 4-ounce ramekins and chill until firm, about 1 hour.
• Whip the remaining 3/4 cup cold heavy cream to stiff peaks. Top each chocolate mousse with whipped cream and serve. (For a softer texture, allow the ramekins to sit at room temperature while you whip the cream.)

Steps:

• Bring chestnuts, milk, sugar, vanilla, and salt to a boil over high heat in a small saucepan. Reduce heat, bring to a simmer, and cook, stirring occasionally, until milk is reduced by one-quarter and chestnuts smash fairly easily against the side of the pot with the back of a spoon, 15-17 minutes.
• Meanwhile, finely chop 4 oz. chocolate. Using a peeler, shave remaining 1 oz. chocolate; set aside until ready to serve.
• Purée chestnut mixture in a blender on high speed until very smooth, about 2 minutes. Add chopped chocolate and 1 tsp. brandy and blend on high speed until chocolate is melted, about 30 seconds. Scrape into a large bowl and let cool to room temperature, stirring occasionally (if lumps form, stir vigorously until smooth), 15-20 minutes.
• Whip 2 cups cream with a whisk in another large bowl until it just barely holds soft peaks. Stir one-third of cream into chocolate mixture to lighten it, then fold in remaining cream just until incorporated. Transfer mousse to a large serving bowl, cover, and chill at least 2 hours or up to 1 day.
• Whip remaining 1 cup cream and 1/2 tsp. brandy with whisk in a large bowl to medium peaks. Garnish mousse with reserved chocolate shavings and serve with whipped cream alongside.
• Do ahead
• Mousse can be made 1 day ahead; cover and chill.

Steps:

• Heat oven to 200C/180C fan/gas 6. Grease a 25cm springform tin, then line the base and sides with baking paper. Whisk eggs and sugar until pale and thick.
• Sift the flour and cocoa together onto the mixture, then gently fold in, followed by the butter. Pour into the tin, ease to the edges, then bake for 8-10 mins until risen and firm to the touch. Cool in the tin.
• Meanwhile, beat the chestnut purée and egg yolks until as smooth as possible. Melt the chocolate in a bowl over a pan of simmering water with half the cream. Remove from the heat, then beat into the chestnut mixture.
• Whisk the egg whites until stiff. In a separate bowl, whip the remaining cream until it holds its shape. Fold into the chocolate mixture, then carefully fold in the egg whites. Drizzle the brandy, if using, over the sponge base, then pour the chocolate mix on top. Level the surface and chill for 5 hrs or overnight until firm. Chill for 2 days, or freeze for 2 months. Thaw overnight in the fridge.
• To serve, carefully remove from the tin, strip off the paper and slide onto a cake stand. Dust heavily with cocoa.
