Beat the eggs, sugar and salt with the whisk of the hand mixer until creamy. Stir in pudding powder, lemon zest, buttermilk and low-fat curd. Grease a springform pan (26 cm Ø) and dust with flour. Pour the mixture into the mould and smooth it down. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 50-60 minutes.
Let rest for 15 minutes with the oven door open. Loosen the cake edge with a knife and let it cool down in the tin. Remove the cake from the mould and dust the edge with icing sugar. Serve with red groats and decorate with mint
