AT A GLANCE
It's pretty hard to beat a featherlight sponge cake and this one's no exception. It's fragrant with lemon rind and filled with a mouth-puckering lemon curd and lightly sweetened crème fraîche. A little candied lemon rind in syrup makes a nice finishing touch, but a simple dusting of icing sugar would also work well.
|01||For lemon curd cream, whisk lemon juice and rind, yolks, eggs and sugar in a saucepan to combine, add butter, then stir continuously over medium-high heat until mixture thickly coats the back of the spoon (4-5 minutes). Remove from heat and stir in gelatine. Transfer to a container, cover with plastic wrap and refrigerate until firm (3-4 hours). Whisk in crème fraîche and refrigerate until required. Lemon curd cream will keep for up to 5 days.|
|02||Preheat oven to 180C. Butter two 22cm diameter cake tins, line bases with baking paper and dust with flour. Whisk caster sugar, eggs, lemon rind and a pinch of salt in an electric mixer until pale and tripled in volume (6-8 minutes). Sieve in flour, cornflour and baking powder in 2 batches, fold to combine, then fold in butter. Divide batter evenly between prepared tins, smooth tops and bake until golden brown and centres spring back when lightly pressed (8-10 minutes). Cool in tins for 10 minutes, then cool completely on wire racks.|
|03||Whisk crème fraîche, cream, icing sugar and vanilla seeds in a bowl to soft peaks and refrigerate until required.|
|04||To serve, spread half the lemon curd cream over one cake, top with half the crème fraîche mixture, then top with remaining cake. Spread with remaining crème fraîche mixture, then, without using a nozzle, pipe remaining lemon curd cream on top and serve.|
