Japanese-Style Sweet Bun Dough

I’ve tried quite a few Water Roux/Tang Zhong methods for making cotton soft sweet bread but by far I think this is the best one. It produces super soft bread and I stay that way for a few days. This time I tried out the recipe from Corner Café website. This is the recipe for basic sweet dough and from the dough you can fill it with all kinds of sweet and savory fillings. This is my simplified method of making the dough but do refer to Corner Café website for his details version.

 

Ingredients:Makes 16 buns

375g bread flour
100g plain flour
35g milk powder
75g caster sugar
3/4 teaspoon salt
1 sachet (7g or 2 1/2 tsp) instant dry yeast
1 egg, lightly beaten
150ml (approx.) lukewarm water – adjust according (I need only 130 ml)
40g butter, cubed

1 egg + a bit of water (for egg wash the buns)


Super soft buns
Water-Roux Paste/Tang Zhong:
25g (just under 2 tbsp) bread flour
125ml (1/2 cup) water

Preparation for the Water-Roux

1. Mix the flour and water in a small saucepan. . Cook over low to medium heat, stirring continuously until it reaches 65ºC. It should have thickened to a paste at this stage, which is when you stir you can see the bottom of the pan. Remove from heat; place a cling film over the paste and leave until lukewarm, or room temperature, before using. (Alternatively if you don’t have a thermometer, cook as before until it starts to thicken, then continue to cook for about 1 more minute before removing from heat.)

Note: This water roux can be kept in an airtight container after cooling in the refrigerator for 1 day if not used immediately. However DO NOT USE if it turns grey in color, that means it has gone bad.

Preparation for the dough:

1. Fit the mixer with the dough hook attachment. Sift bread flour, plain flour, milk powder, caster sugar and salt the mixing bowl. Add in the yeast and mix well. Add in the water roux and beaten egg. Turn on the mixer and slowly add in the lukewarm water until the dough form into a nice ball of dough. (You might not need all the water. I used only 130 ml of it)
2. Continue to knead for 10 minutes and add in the butter. Continue to knead until all the butter is incorporated into the dough and the dough is smooth and elastic. Take the dough out from the mixing bowl and give it a final few kneading by hand. Form it into a round ball and let it to rise until double in size in a large greased bowl. Cover the bowl with a wet towel or cling wrap (It took me an hour to proof the dough but it all depend on the weather and environment on the day you make the bread)
3. Punch down the dough gives it a few knead and divide the dough into 16 equal portions. The easiest way to divide is to cut the dough into 4 parts and from there divide each into another 4 portions. Form each into a ball and let it rest for another 10 minutes.
4. Shape and fill the buns with fillings. Place the buns in baking sheets that line with parchment paper. Cover the buns and let it rise until double in size (it takes another 30-40 min) Brush the buns with some egg wash.
5. Bake in a pre-heated 350 degree for 15-20 minutes or until golden brown.
