Once the lotus paste and dough have cooled, prepare the lotus paste, mooncake skin dough, and salted duck egg yolks, if using.
Using a kitchen scale, weigh the filling for each mooncake.
If using a salted duck egg yolk, place one yolk and enough lotus paste on the scale so the combined weight is 30 g.
Adjust the amount of lotus paste as needed to reach the correct weight.
If omitting the salted duck egg yolk, use 30 g of lotus paste for each mooncake.
Weigh the mooncake skin dough with the filling.
The total weight of the filling and mooncake skin dough should be 50 g.
Adjust the amount of dough as needed.
Roll the lotus paste into a smooth ball.
Flatten the lotus paste into a disk.
Place the salted duck egg yolk in the center of the disk, if using.
Enclose the salted duck egg yolk completely with the lotus paste.
Roll gently between the palms of the hands to form a smooth ball.
If using only lotus paste, roll the measured lotus paste directly into a smooth ball.
Roll the mooncake skin dough into a ball.
Flatten the dough into a disk.
Place the lotus paste ball in the center of the dough disk.
Gently stretch and press the dough around the lotus paste filling until fully enclosed.
Roll gently between the palms of the hands until smooth.
Repeat the process with the remaining lotus paste, dough, and salted duck egg yolks.
