These mooncakes originate from Teochew (潮州), China. The Teochews favour yam or taro, and make wonderful desserts and dishes from this root. The filing is very similar to their Or nee (芋泥)that many in Asia are familiar with.

Like many Asian filings, these are done by simply steaming the root, mash it  and then caramelizing sugar into the mash. Fat (often pork lard) is added. Alternatively, we can use shallots fried in vegetable oil to get this umami flavour into the dessert.

I have made mine bite size this time, because I found cutting the mooncake somewhat too untidy, with flakes all over the place. It tastes simply wonderful!

Ingredients

Pastry
Water Dough

250g Plain Flour

120g Water

65g Fat (Vegetable shortening is the best)

1 Tbsp Sugar

1/2 tsp Salt

Oil Dough

180g Cake Flour (or low protein flour)

45g Fat (Butter gives the best fragrance)

45g Oil (Any cooking oil)

Filing

300g Yam (peeled, cubed, steamed and then mashed)

100g Sugar (I use raw sugar)

50g Oil

1 Big Onion or 15 shallots (skined and sliced)

A pinch of salt

Cooked Salted Duck Egg Yolk (steamed or baked)

Method

    Make the filling
  1. Heat a pan with the oil and fry the onions until light brown. Remove the oil and onions and set aside.
  2. Using the same pan and medium heat, add the mashed yam and sugar, until sugar melts.
  3. Add the oil and onion and mix well, until it forms into a dough.
  4. Make oil dough
  5. Put everything into a blender for 1 to 2 minutes, or until it comes to a dough.
  6. Make the water dough
  7. Put everything into a blender for 1 to 2 minutes until it comes to a dough.
  8. Shape the mooncakes
  9. Divide the oil dough and the water dough into 15 equal portions each, the filing into 30 equal portions.
  10. Place each oil dough within each water dough and seal.
  11. Roll out the dough to a long oval, to about 3 mm.
  12. Roll it up from the short end like a swiss roll.
  13. Roll out the dough again to a long oval to about 2mm.
  14. Roll it into a swiss roll. Do the same for the rest of the 14 pieces. Rest for 15 minutes.
  15. Cut the roll into 2, revealing the spiral.
  16. Press the roll down using the palm, cut side up.
  17. Wrap each portion of filing into each dough.
  18. Bake for 15 minutes at 220°C. Do not egg wash or you will destroy the spiral pattern.

Here’s a video of how I did my flaky mooncakes. Hope it helps you get yours done!

There are not many good videos on the internet that shows you how to do this well. However, I managed to find this one. This lady has one of the better techniques, and because she uses coloring, you can see what she is doing better. Having said that, I don’t believe in using colouring in foods, so take it easy on that.
