How to make Basic Sponge cake sheet Genoise

Instructions

1. Sift the soft flour.
2. Put eggs in a bowl and beat lightly, then add sugar and starch syrup and mix.
3. Put the bowl in 60-70℃ warm water and stir with a whisk. When the egg water reaches 40℃, take it out of the bowl.
4. With a hand mixer, whip up the eggs until the egg becomes ivory in volume.
   When the mark that fell on the floor stays for more than 3 seconds, it's done! Finally, whip at the lowest speed of the hand mixer to clear air bubbles.
5. Divide the sifted flour 2-3 times and mix lightly and quickly.
6. Add a little dough to the melted butter + milk and mix, then pour into the accompaniment and mix quickly.
7. Drop the dough into an oven pan lined with parchment paper from a high place, and gently slap it on the floor to clean up any air bubbles on the surface.
8. Bake for 30 minutes in an oven preheated to 170 degrees.
