Rhubarb Mascarpone Mousse Cake Recipes

Steps:

• Heat oven to 200C/fan 180C/gas 6. Cut the rhubarb stalks in half lengthwise, then into finger-length pieces. Put in a shallow ovenproof dish, then pour over the wine. Tuck the orange zest and star anise among the spears then sprinkle with sugar.
• Cover tightly with foil and roast for 20 mins, until the rhubarb is tender. Uncover and cook for a further 5 mins to reduce the sauce until syrupy.
• Serve the rhubarb on small plates with a spoonful of mascarpone on the side.

Steps:

• Make cake:
• Preheat oven to 350°F and place rack in center.
• Butter 9-inch cake pan and line bottom with a round of parchment.
• Butter paper, then dust pan with flour, knocking out excess.
• Sift together flour, baking powder, and salt into a bowl.
• Beat butter and sugar together at medium-high speed until pale and fluffy, about 2 minutes.
• Beat in egg and vanilla until fluffy and combined well, about 2 minutes.
• Reduce speed to low and add flour mixture and milk alternately in 3 batches, beginning and ending with flour. Mix until batter is just combined. Do not overmix.
• Spread batter evenly in pan and bake until cake begins to pull away from sides of pan and a wooden pick or skewer inserted in center comes out clean, 20 to 25 minutes (cake will still be pale in color, not golden brown).
• Cool for 10 minutes in pan on a rack, then invert onto rack and reinvert to cool completely right side up.
• Make mousse while cake is baking:
• Combine rhubarb, 1 1/4 cups sugar, and 1/4 cup water in a large heavy saucepan and cook over medium-high heat, stirring occasionally, until rhubarb releases enough juice to almost cover rhubarb, 5 to 8 minutes.
• Reduce heat and simmer mixture, stirring occasionally, until rhubarb falls apart and is reduced to about 4 cups, 25 to 30 minutes. Remove from heat.
• Pour mixture into a large fine-mesh sieve set over a bowl and collect 1 cup syrup and set aside. Transfer rhubarb pulp to another bowl.
• Soften gelatin in remaining 1/4 cup water 1 minute, then stir into hot rhubarb mixture until dissolved.
• Set bowl inside a larger bowl of ice water and stir rhubarb mixture until cooled to room temperature (do not let set on ice).
• Beat together mascarpone, heavy cream, and vanilla with remaining 1/4 cup sugar until it just holds stiff peaks.
• Fold cooled rhubarb mixture into mascarpone mixture.
• Assemble mousse cake:
• Carefully halve cooled cake horizontally, then spread jam on bottom half and reassemble.
• Invert bottom of spring-form pan (to make it easier to slide cake off bottom), then lock on side. Lightly oil bottom and sides of pan with some vegetable oil.
• Arrange cake in center of spring-form pan. Spoon rhubarb mousse into pan over cake. Smooth top. Rap pan on counter twice to release any air bubbles and chill cake, uncovered, until mousse is set, at least 2 hours.
• Make glaze:
• Sprinkle gelatin over water in a small heavy saucepan to soften, 1 minute. Heat gelatin over low heat until it has dissolved. Remove from heat then stir in reserved rhubarb syrup.
• Pour glaze over chilled mousse, tilting pan slightly to cover it completely in an even layer. Chill, uncovered, until glaze is set, at least 1 hour.
• To serve:
• Let cake stand at room temperature 30 minutes to soften slightly. Wrap a kitchen towel dampened in hot water around the side of the pan for about 15 seconds. Run the tip of a thin knife around the edge of the pan, then gently unlock and remove sides of spring-form pan.
