Bread Talk - Yukone Method Sweet Soft Buns

 

the Yukone(Water Roux, 汤种) method is a brilliantly simple technique to make very soft and springy buns that will retain its softness for days! I am still baffled by how the addition of just a small lump of flour mixed with hot water can have such an amazing effect. I intend to find out more.  

The most classic way of water roux method requires one to 'cook' a small portion of flour with water from room temperature to 65C. Once the temperature of the roux reaches 65C, heating is stopped.

Then variations started to emerge where boiling hot water is poured directly into a small portion of the flour. (well, I guess, by the time the flour is mixed with the water, the mixture will probably cool very quickly to around the same temperature) This is mixed well and let to 'proof' over night.

The method I use is the latter method - perfect for a lazy bum like me. A variety of dried materials can be used - from just purely bread flour, to a mixture of bread flour/ plain/cake flour/ milk powder/ whole wheat flour... the possibility is endless.

The recipe I am using here is a combination of Valerie's formula with Alex Goh's recipes. For the filling, I am using the Spicy Fried Dried Shrimps from my last post - but there is really a whole range of variation that one can play with.

Looking at these soft sweet buns, I am happy with the results but I am still trying to figure out how the wrinkles appear overnight.... if anyone has insight to this, please do enlighten :)

 

Recipe : (Soft Buns)

Water Roux
Bread Flour                 50g
Boiling water                75g

Bread Dough
Active Dry East           6gm

Salt                             2gm
Water                         50gm

Butter                          40gm

Method :
1. Mix water roux ingredients together in a bowl. Cover bowl with cling wrap and store in fridge for 12 hours.
2. In a mixer fitted with a bread hook, add flour, yeast, sugar, egg and water. Start mixing at slow speed for  2 mins. Add salt and continue to knead until dough lifts from the wall of the mixing bowl.
3. Add (1) and continue to knead for 3 mins. (I am using Kitchenaide speed 2)
4. Add butter and increasing kneading speed to speed 4.
5. Continue kneading for 15 mins on speed 4 until dough is no longer sticky and does not break when pulled to perform window test.
6. Place dough in a slightly oiled bowl. Cover with cling wrap and leave to proof in a warm area for 45mins.
7. With lightly floured hands and table top, knead (6) to form a smooth round ball. Divide dough into 12 balls - about 40g each.
8. Roll each small ball into a round ball and leave to proof for 10mins.
9. Flatten each ball and roll out to a circle with a rolling pin. Place 18g of Hei Bee Hiam filling in the center of the dough and wrap and seal the edges of the dough to form a ball.
10. Leave to proof for 1 hour.
11. Brush with egg white and decorate.(I used a Sakura ebi shrimp)
12. Bake at 185C for 8-10mins until brown.
13. Leave to cool.
