Preparation

• Preheat oven to 200C. Line the base of 2 9" round cake pan with non-stick baking paper. Grease the sides of the pan.
• Use an electric beater to beat the eggs and sugar in a medium bowl until thick and pale, and a ribbon trail forms when beaters are lifted. Use a large metal spoon to gently fold in the flour mixture. Do not overfold as you don't want to deflate the batter.
• Spoon mixture into the lined pan and smooth the surface flat. Bake for 13-15 minutes or a skewer inserted into the center comes out clean. Immediately turn the cake onto the paper-lined rack and remove the baking paper. Leave cake to cool completely. You can make the cake a day ahead.
• For Mango Mousse:
  Sprinkle gelatin on mango puree and set aside until spongy. In a separate bowl whisk the egg yolks and sugar until thick and pale (about 2 - 3 minutes) and set aside. Put milk into a pot and bring to a simmer. Remove milk and slowly pour into the egg mixture, stirring at the same time so as not to scramble the eggs. Sieve the mixture and pour it back into the pot. Return the mixture to pan and cook over medium heat, stirring constantly until it thickens. Do not bring to boil or mixture will curdle. Immediately remove from heat and add the mango gelatin mixture. Stir to mix completely. Place mousse over a bowl of ice water. Add in lime juice and yellow food coloring. Let cool, stirring occasionally until the mousse thickens to resemble softly whipped cream. Pour thickened cream into a bowl and whip until soft peaks. Fold the whipped cream into the mousse mixture. Place mixture in the refrigerator.
• For Mango Mirror:
  Place mango flesh, sugar, and 50 ml water in saucepan. Cook over low heat, crushing the flesh with back of a spoon to start juices flowing. Simmer for 10 minutes. Pour through a colander and drain into a bowl. Do not press down the pulp too much or your mango mirror won't be shiny because of the pulp. Place lime juice and extra water in a small bowl. Sprinkle gelatin over this mixture; set aside until spongy. Put the mango juice into a pan and bring to a simmer. Pour over the gelatin mixture and stir to dissolve. Tint to desired color with yellow food coloring. Place bowl over bowl of ice water and stir occasionally until the mixture is syrupy and just beings to thicken(do not let jell).
• To Assemble the Cake:
  Lightly grease a 9" springform pan and line the bottom with parchment. Cut out a cardboard circle that is exactly the same size as the bottom inside of the pan. Cover cardboard with aluminum foil and fit into bottom of pan. Center one layer of the cake bottom of pan. Pour about half of the mousse over the first layer of cake in the pan. Refrigerate for 2-3 minutes to firm the mousse a bit. Set the next layer of cake on top of the cream. Pour the remaining mousse over the cake and smooth the top with a patula. Refrigerate for about 2 hours (or overnight) until the mousse sets. Prepare the mango mirro. Pour over the top of cake. Refrigerate until set.
• To Serve:
  Wrap a hot towel around the outside of springform pan for a 2-3 minutes. Run a small sharp knife tip around the edge of the cake to separate it form the sides of pan. Mirror will tear when sides are unlatched if it is stuck at any point. Slowly unlatch the pan. Slice cake into wedges.
