AT A GLANCE
"This is our take on a traditional Uruguayan dessert. It's usually served with tinned peaches, but at Christmas it's got to be mangoes."
|01||For meringues, preheat oven to 100C. Whisk eggwhite and a pinch of salt in an electric mixer until soft peaks form (3-4 minutes), then, whisking continuously, gradually add sugar and whisk until firm and glossy (2-3 minutes). Whisk in cornflour and vinegar, then spoon into rough 10cm-diameter mounds on baking trays lined with baking paper. Bake until crisp but not coloured (1½-2 hours), cool completely, break into chunks and store in an airtight container until required.|
|02||For sponge cake, increase oven to 180C. Whisk eggs and sugar in an electric mixer until pale and fluffy (5-6 minutes), then sieve over flour and fold to combine. Fold in melted butter, then spread in a 25cm x 35cm cake tin buttered and lined with baking paper. Bake until cake is light golden and centre springs back when lightly pressed (20-25 minutes), cool completely, then break into large pieces and store in an airtight container until required.|
|03||Meanwhile, combine sugar and 300ml water in a saucepan, stir over medium-high heat until sugar dissolves. Bring to the boil, add reserved mango seeds, remove from heat and stand for 15 minutes. Strain into a bowl (discard seeds), add mango cheeks and refrigerate until well chilled (2-3 hours).|
|04||Meanwhile, reduce oven to 150C. Spread peanuts on an oven tray and roast, stirring occasionally, until golden (4-5 minutes).Transfer to a bowl, add oil and 2 tsp fine salt, stir to coat, cool. Coarsely chop and set aside.|
|05||Arrange meringue, sponge cake, mango, and spoonfuls of cream and dulce de leche on a serving plate, scatter with roast peanuts and serve.|
