Instructions
- 1
You will also need a 150g to 185g mooncake mold.
- 2
Steam purple yam for 10 minutes until very soft.
- 3
Remove and puree with an immersion blender while still warm. Do the same for sweet potatoes.
- 4
Combine pureed purple yam, ¼ cup (60ml) vegetable oil, and ¼ cup (55g) granulated sugar in a nonstick fry pan. Cook over low heat until sugar has melted and vegetable oil is fully incorporated into the purple yam puree. This should take about 2 to 3 minutes. Do the the same for sweet potatoes but use only 2 tablespoons vegetable oil and 2 tablespoons granulated sugar.
- 5
Toast kuachi (melon seeds) over medium heat for about 2 to 3 minutes. Remove and allow it to cool. Mix into purple yam paste.
- 6
Divide and form sweet potato paste into 6 balls of 1¼ oz (35g) each. Divide and form purple yam paste into 6 balls measuring approximately 3 oz (85g) each. Wrap each portion of purple yam paste over each portion of sweet potato paste to form 6 balls of filling weighing (4¼ oz) 120g each.
- 7
Combine golden syrup, vegetable oil, and alkaline water in a small bowl or measuring cup.
- 8
Sift cake flour into a large bowl. Make a well in the center. Pour syrup mixture into well and mix with a spatula to form a soft dough. Cover with shrink wrap and let dough rest for 30 minutes.
- 9
Lightly dust work surface with cake flour. Knead dough until smooth adding a little flour if necessary. Divide into 6 portions of 50g each. You will have roughly 100g excess dough.
- 10
Take a portion of the dough and spread it into a circle of about 4 inches (10cm) with your fingers. Alternatively, you can roll it out with a small rolling pin.
- 11
Wrap a ball of filling with the dough. Roll the ball of dough and filling between your palms to smoothen.
- 12
Place into flour dusted mooncake mold. Press to conform to the shape of the mold.

Place on work surface and carefully press spring stamp down to get a nice pattern on the top. Lift mold and gently release mooncake onto your palm.
- 14
Place on a parchment lined baking tray. Repeat with the remaining dough and filling.
