Ingredients

Scale

Yudane – optional

80g bread flour

64g hot water

Dough

550g bread flour

165g milk

40g water

60g egg white (the whites of 1 large/jumbo egg)

74g sugar

10g salt

100g active sourdough starter

53g butter (I use salted)

Instructions

Step 1 – Preparation

Feed Your Sourdough Starter

Prepare Yudane

  • This recipe can be made with OR without the yudane.
  • Yudane is basically a bread improver –it will help your bread be lighter, softer, fluffier and moist for longer
  • In a bowl, add 80g of bread flour, then pour 64g of boiling hot water, mix
  • Let cool, cover, put in the fridge overnight

Step 2 – Mixing

  • In your stand mixer, mix dough ingredients (except the butter) until you get a windowpane (mixer at speed 2 for around 10-16 min)
  • Then add in the butter. Mix again until you get a windowpane (mixer at speed 2 for around 10-16 min)

Step 3 – Bulk Proof/1st Rise

  • Roughly shape the dough into a taut ball and put it in a greased bowl, cover
  • Bulk proof for 4hrs at 74F (gauge time if your room is cooler or warmer)

Step 4 – Cold Proof/2nd Rise

  • Cold proof in your fridge overnight (~8hrs)

ATTN – Cold proofing is optional. I like cold proofing because the slow fermentation lets flavors develop.  It’s normal that it doesn’t rise much or at all in the fridge.  The cold halts fermentation.  The rule of thumb here is to bake when it’s 80% in size, however long that takes in the fridge or on the counter.  My starter leavens this dough with the times I listed above.  It may be shorter or longer for you depending on your starter’s strength.  

Step 5 – Shaping

  • Take out the dough, weigh and divide equally by 6 and shape tautly into buns
  • Cover, rest 20 min
  • Roll each bun into a rectangle
  • Fold the rectangle into thirds like you’re folding a piece of paper to mail (the envelope fold)
  • Cover, rest 20 min
  • Roll each long into a long rectangle
  • Now roll each rectangle like you would a cinnamon roll
  • Lift each roll and place into your buttered Pullman loaf pan
  • Then put directly onto a buttered 13 x 4 x 4 Pullman Loaf Pan
  • Cover

Step 6 – Final Proof/3rd Rise

  • Cover lightly because we don’t want it to dry out
  • Final proof this for 4-6hrs at room temp (74F),
  • or until *ALMOST* double, around 75-80% rise

Step 7 – Baking

  • Egg-wash and bake in a pre-heated 350F oven for 35-40 min

Notes

The original version of my recipe called for a sweet stiff starter –though I prefer using this type of starter so that we don’t get any sourness at all, it IS much faster if you use a regular sourdough starter fed at 1:1:1.  So I have updated this recipe using that instead.

This recipe at scale 1x will make

  • 6 logs in a 13 x 4 x 4 Pullman Loaf Pan, OR
  • 3 logs in a 8 x 4 x 4 Pullman Loaf Pan –but it will be VERY high

To make this sourdough bread in an 8 x 4 x 4 pan with a normal height, please make this recipe at ½ the scale –in other words, divide this recipe in half

      Egg wash is commonly just known as 1 egg (optional splash of water/milk), beaten and brushed on

    Could you use 1/2 whole wheat and add vital gluten to increase protein content to bread flour?

      You can certainly use those flours… will it still work and taste good? YES! Will it be the exact same as you see in the pics and my IG reel? No, but that’s ok. What “whole wheat” lacks in fluffiness and volume (airy, puffy bread) –makes up for it with flavor

    Do you add the yudane when mixing all the rest of the ingredients but butter?

      Yes, mix the dough and the yudane to windowpane, then add the butter and mix that windowpane. This is important for that extra tall and fluffiness. I have done it without doing this it was still okay –still bread, but it was not tall and flully and cloud-like.

    I might be missing something. I can’t find in the instruction where I mix the yudane in. Do I mix it in with the dough when I’m making it?

    Hi there, I’m making your Sourdough Bread Recipe: Sourdough Japanese Milk Bread, the dough doesn’t rise on the fridge… it’s normal? Can I put on the counter and wait until it double in size? In the first 4 hour rise at 25 degrees the dough only rose 25%, then I put it in the refrigerator, can you tell me what I should do? Thank you for your help…I’m a sourdough beginner…
