20g corn flour
1/4 tsp baking powder
1/8 tsp bicarbonate of soda
4 cooked salted duck egg yolks
170g butter, softened (I used scs)
80g icing sugar
1/2 tsp salt(I omit)
Glaze: 1 egg yolk
Topping:Black and white sesame seeds
Method:
- Sift together plain flour, corn flour, baking powder and bicarbonate of soda and set aside.
- Using an electric mixer, beat butter and sugar till sugar is dissolved.
- Add in the mashed salted egg yolks and sifted flour, mix to a soft pliable dough (mine is not pliable, soft but manageable). If dough is too soft, wrap in cling film and keep in the refrigerator for 30 mins.
- Line baking tray with baking paper and preheat oven to 170C
- You can divide the dough into 2 and then keep one dough in the fridge while you are working on the other dough. Place the dough between 2 plastic sheets and roll out dough to 5mm thickness ( i rolled mine to 2-3mm as it will expand a little bit during baking ) and cut them using your desired cookie cutter. Apply glaze , sprinkle some sesame seeds and bake for about 15-20 mins ( The dough is quite soft and i have used a small spatula to lift them up to the baking tray and i baked mine for 20 mins.)
