  and  
here, they really made me want to try making this bread so much. I sincerely thank Lee Shifu for sharing her expensive recipe with us. Lee Shifu had spent four years tracking this recipe and spent more than 4 thousand dollars to buy it. I am very thankful because I don't have to spend a single cent nor energy to get this recipe. I also want to thank Victoria for translating and sharing this awesome recipe with us.
These are the sweet buns. They are soft and so good to eat.
Recipe:
Ingredients: (Below is half of the original recipe)
Starter dough:
105 g bread flour
45 g plain flour
12 g castor sugar
3 g instant yeast (1/2 tsp + 1/4 tsp)
120 g water
Main Dough:
105 g bread flour
45 g  plain  flour
48 g sugar
1/2 tsp salt
12 g milk powder
45 g egg
27 g water
36 g unsalted butter, softened
Method:
1)  Mix and combine all the stater dough ingredients together. Allow to sit in a warm place to rise till it looks like "honeycomb". (It took me 2 hours).
2) In a mixer with a dough hook, combine the above with main dough ingredients except butter,  knead till it is shinny and non-sticky.  Add in butter, knead till it is shinny and pliable.
3)  Rest the dough till it doubles in size. ( for my own reference only: about 60 minutes).
4)  After dough has risen, punch down gas and without resting dough ,divide it into 6 equal portions and roll each into round shape. Place them on a lightly greased baking pan (18 cm x 28 cm).
5) Allow to rise till doubles in size (for my own reference only: about 45 minutes - 60 minutes)
6)  Brush with egg wash. Bake in a preheated oven at 180 deg C for 25 - 30 minutes.
