From 'The 65 C Bread Doctor" by Yvonne Chen        
           
           
Water Roux Starter          
           
any amount is fine bread flour 50 g    
as long as the 1:5 ratio is followed water  250 g    
           
  Whisk both until well mixed        
  Heat it up on stove, keep stirring         
  until temperature reaches 65 C or 149 F        
  (Yippee uses the microwave, about 4 minutes, stir halfway.)     
  (Final product should leave a trail when stirred.)      
  Put a plastic wrap directly on top to prevent forming a 'skin'.    
  Must be cooled to at least room temperature before use.    
  Refrigerate up to 3 days.          
  Do not use if turns grey.        
           
           
Makes 2 loaves          
Original recipe uses water roux starter only, sponge not necessary.         
Yippee threw in an additional step of developing the sponge out of the total, see side column for her portions.    
           
          Yippee's Sponge
A. bread flour 540 g   400
  sugar 86 g    
  salt 8 g    
  yeast 11 g   8
B. whole eggs 86 g   86
  whipping cream (can substitute with either half n half or milk) 59 g   59
  milk 54 g   54
  milk (recipe calls for flavor enhancer but Yippee uses milk instead) 9 g   9
           
  water roux starter 144 g   2 TBSP out of the 144g
C. butter 49 g    
           
Mix: Combine A. and B. until a ball is formed.         
  Add C. and knead until the dough passes the windowpane test.    
  (Yippee says:  use your judgment, each machine is different)    
  (Yippee kneads her dough in her Zojirushi breadmaker for 30 minutes.   
           
1st Fermentation: About 40 minutes at 28 C or 82.4 F, 75% humidity    
           
Scale:  into 4 pieces if making twin loaves, each at 265g      
  (Yippee makes 2 log loaves, each at 530g)        
Rest:          
  15 minutes at room temperature        
           
Shape: For twin loaves:        
  Degas        
  Roll into an oval        
  With the long side facing you:        
  Fold 1/3 from top to bottom, press to seal        
  Fold 1/3 from bottom to top, press to seal        
  Turn seam side down        
  Roll and elongate the dough to about 30cm or 12 "     
  Upside down and roll into a cylindrical shape      
  Seam side down, into the loaf pan        
           
  For log loaves:        
  Shape like regular sandwich bread        
           
Final Proof: About 40 minutes at 38 C or 100.4 F, 85% humidity     
  (Yippee lets the dough rise for 20 more minutes to get a taller loaf)    
           
Bake: Whole egg wash, no water added        
  350 F, 35-40 minutes        

 

 

Sponge preparation:

 

a.                   Use the ingredients listed on the side column, mixed until all are well incorporated

b.                  Leave at room temperature ~ 76-80F for an hour

c.                   Grease a food grade plastic bag, pour dough in, leave enough space to allow the dough to expand to about 160% of its size, reinforce the bag with double or triple bagging before tightening it, retard overnight

d.                  Subtract the above ingredients from the main formula, whatever remaining will be mixed at the 'Mix' stage with the sponge.  Follow the rest of the formula. 

 

However, if your dough feels cold after mixing due to the refrigerated sponge, instead of following the time suggested in the formula, watch your dough:

 

1st Fermentation:           Completes when the dough has risen to about 180% of its size

 

Final Proof:                   Completes when a dent is formed and very slowly bounces back

                                    when dough is poked with a floured finger

 

 

To make rolls:

Scale: 60g each

Bake: 350F, about 15 minutes

rest of the procedures unchanged

Choice of fillings, if preferred: bacon, roast chicken, cheese, red bean, pork, curry and custard cream.

Hi, Judy:

I did that for easy calculation.

I try your recipe. It worked out very good and my kids love it. My loaf never expand like this before, I can see it. But, I need a bit of practice to shape my dough.

Hi, Laddavan:

Practice makes perfect, it's so true, especially when comes to making bread.
