TIPS & NOTES
✿ Let the mooncake rest for 2 days at room temperature. It will result in a very soft and moist golden skin.
✿ Depending on the oven temperature might vary. If the skin cracks the temperature of the oven is too high.
✿ You can eliminate or add more salted egg yolk crumbs to the custard or lava, to adjust it to your personal preferences.
✿ To store the mooncake you can freeze the mooncakes after pressing them. Bake them when ready to consume!
✿ If already baked, they’re best to consume within a week.
