1. Put the eggs, which are at 40 °C / 104 °F, sugar, inverted sugar and
   salt in the mixing bowl. Whip at maximum speed until light and fluffy.
2. In a separate mixing bowl combine the sifted flour and potato
   starch with a whisk, add into the whipped mixture. Carefully fold in
   the dry ingredients with the whisk to keep maximum volume. Try to
   avoid incorporating air bubbles.
3. Melt butter in a microwave oven to 45 °C / 113 °F. Mix it with a bit of
   the sponge cake batter using a whisk.
4. Pour the butter mixture to the rest of the sponge cake batter. Whisk
   everything again.
5. Place a cake ring d=18 cm and h=6 cm on a baking sheet lined with
   a perforated silicone mat. Pour the cake batter into the ring.
6. Bake the sponge in the oven, preheated to 180 °C / 356 °F, for
   around 20-25 minutes. When ready, the sponge should be golden-
   brown and spring back when pressed.
7. Let it cool down at room temperature.
8. Cut the sponge out of the cake ring and trim the top crust using a
   serrated knife.
9. Slice the sponge cake into three layers as desired.
