Shokupan is a delicious, soft, white and fluffy bread made using the Yudane method. This pre-rising technique involves scalding white high protein bread flour with hot boiling water, mixing into a dough, and setting aside for several hours or overnight. Adding hot boiling water gelatinises the starch in the flour. The swollen, gelatinised starch not only allows the starch to take in more water, increases the elasticity of the dough and increases its sweetness. Using the Yudane method for the bread dough, makes the bread softer, moist and sweeter, with a fine and delicate crumb. The bread also lasts longer.
For the Yudane method the flour to water ratios is generally 1:1. Start by mixing the flour with about 1/4 of the water, from your hot water tap. Then, add the remaining 3/4 of the water as hot boiling water. Mix the dough with a wooden spoon or spatula. The ideal temperature for the mixed dough should be about 120 degrees F (50 degrees C). Allow the dough to cool down and then, wrap with a sheet of cling wrap or a warm cloth. Set it aside on your kitchen bench, or in a fridge for several hours or overnight, to complete the gelatinisation process.

Method
Make the Yudane the day before by placing the bread flour in a bowl. Add 1/4 of the water as hot water from your tap. Mix with the flour. The add the rest of the water as boiling water and combine well. Cover the bowl with a towel or plastic wrap and set aside in your refrigerator overnight. On the next day bring the Yudane to room temperature. Make the bread by firstly pouring the milk at room temperature into a stand mixer bowl. Add the butter, sugar and yeast to the bowl. Then, add small pieces of the yudane torn or cut from the dough ball. Mix briefly and then add the salt and bread flour. Using the kneading hook attachment or your mixer, combine all ingredients well using a low speed. Then, knead the dough for 15-20 minutes by increasing the speed to moderate. Remove the dough and knead briefly by hand and shape into a ball. Place the dough into a greased bowl. Cover the bowl with a towel or cling wrap. Let the dough rise for about 45 -60 minutes at about 85 degrees F (30 degrees C), or until the dough doubles in size.
Next, press the dough down to break the larger bubbles in the dough. Then, cut the dough into two equal parts and roll them into thick cylinders. Cover the rolled dough balls with a wet cloth, or place them in a covered greased pan and set aside for 20-30 minutes to rise further.
Then, roll out each dough piece into a thick rectangular shape about 6 × 8 inches (15 x 20 cm) in size.
Roll the dough tightly into the centre from each end. Rotate the dough 90 degrees and roll it up from one end. Prepare two small loaf bread tins by spraying lightly with cooking oil. Add the rolled dough to the pans. Cover each tin with a wet cloth, and allow the dough to rise in a warm place for 20-30 minutes, or until the dough rises almost to the top of the tin.
Meanwhile, preheat your oven to 365 degrees F (185 degrees C). Bake the dough for about 25-30 minutes, until brown on the top and cooked right through. Remove the pans from the oven and gently turn-out the loaves from the tins, Cool the loaves on a rack. You can brush the tops with whisked egg when hot for a darker and shiny finish.
