To make the wrapper

1. Combine lye water, golden syrup, and vegetable oil in a small bowl and then mix with flour. Stir until well combined. Wrap with plastic wrapper and then knead several times until smooth. Set aside in fridge for 2-3 hours.
2. Transfer out and then divide into 14 equal balls (each one 15g)

Assembling

1. Measure the fillings for egg yolk mooncake: paste+ egg yolk=35g. Measure the fillings for pure paste filling: paste filling=30g. Wrap the egg yolks with paste firstly. And shape all the filling into round balls. Take one portion of the wrapper, press into a round wrapper and then place one filling ball in center. Push the wrapper from bottom to top little by little until the whole ball is completely sealed. Shape it into a round ball firstly and then into an oval.Slightly dust your mooncake tool and press the rod and gently remove the cake from the tool.
2. Preheat oven to 180C (356F). Spray a very thin layer of water on surface to avoid cracking surface (especially you used larger amount of dusting flour). Bake for 5 minutes.
3. In a small bowl, whisked the egg yolk and combine with egg whites. Transfer mooncakes out and brush a very thin layer of egg wash on the surface.
4. Continue bake for around 15 to 20 minutes until the mooncake becomes well browned.
5. Transfer out to a cooling down crack to cool down completely. Place in an airtight containers. Wait for around 1 or 2 days for the pasty to become soft and oily. After the "oil return" process, keep the mooncakes in fridge up to 2 weeks.
