Ingredients

• 400g bread flour
• 6g instant active yeast(high sugar)
• 40g white sugar
• 60g beaten egg
• 40g condensed milk
• 220g milk
• 35g butter (cube)
• 6g salt

Filling

• 350g red bean paste (I bought mine from Phoon Huat), divide into 10 balls weighing 35g each. cover and set aside.

Other

• 28cm x 28 cm lined with non stick baking sheet
• 1 whole beaten egg + 1 tbs water (mix well for egg wash)
• some white sesame seeds

Method 

• Preheat the oven at 160 degree celsius
• Lay the baking paper on the tray
• Add all the bread flour, yeast and sugar into the mixer followed by the wet ingredients (eggs , milk and condensed milk)
• Use a J hook to knead the dough at low speed. Knead until dough is formed
• Add in the butter and knead for about 2 minutes at speed 2 ( low speed)
• Add in the salt and continue to knead at speed 2. Knead until you reach window pane stage. This will take about 15-17 minutes depending on your machine. I am using Kenwood ChefXL titanium. The window pane stage is essential (refer to picture below)
• Remove from the mixer, cover the dough and let it rest for 5 minutes. Please refrain from adding more flour unless it is way too sticky for you to handle. Initially the dough would be somewhat tacky but not way too sticky to handle, I didn’t need to add any flour at all on my end.
• Divide the dough into 10 balls . Wrap the filling inside the dough and roll it into a ball. Do the same for the rest of the dough. Cover and let it rest for 15-20 minutes
• Flatten the dough using your palm. Then roll it out into elongated shape, like a cow’s tongue. See photo below.
• make 7 slits like the photo shown below
• flip the dough to the other side , the slits will be at the back and bottom part, thin out the bottom part by pressing it in downward motion. then start rolling from the top . As shown on the photo below. Lay it on the tray . Do the same for the rest of the dough. Make sure to leave some spaces in between the dough to expand nicely. See photo below. Cover and let it proof til the size becomes double. This should take about 45 mins to an hour . The timing is just a guideline. This may take longer or shorter depending on your environment.
• Brush with egg wash and sprinkle some white sesame seeds
• Bake for 23-25 minutes.
• Let it cool down for 15 minutes before transferring it on the wire rack
