Chocolate Filling
1.
Add the fine sugar to the eggs and beat them evenly with a manual whisk.
2.
After beating, add 60 grams of milk and mix well.
3.
Flour, orange powder, and cocoa powder are mixed and sift into an egg bowl and mix well.
4.
Bring the water to a boil and keep the egg-beating bowl off. Add chocolate to the egg beater to keep stirring the mixed batter. (First stir with a manual whisk, and then use a spatula after stirring a little thick). Turn the heat to medium. At this time, the temperature of the egg-beating basin is a bit high. Be careful of being burned. You can wrap the egg-beating basin with a damp cloth and stir constantly with the scraper to avoid large pieces of agglomeration. Stir until formed. The egg beater leaves the pot. Cover with plastic wrap and refrigerate for later use.
