First add the flour and starch and sift them.
Beat the eggs with the sugar, with an electric whisk, for at least 10 minutes or until you get a very swollen and clear mixture.
Then gently mix in the flour and starch, one spoonful at a time.
Once you have a uniform mixture, pour the mixture into a mold lined with parchment paper.
Bake for about 40 minutes in a static oven, preheated to 170 ° C.
