SOURDOUGH HOKKAIDO MILK BREAD WITH TANGZHONG

Steps:

• See the Photo Gallery below for step-by-step process photos.
• Starter
• Mix the starter ingredients in a straight-walled, transparent container with space for at least 50% growth. (See photo gallery where 150ml grows to approximately 225ml in a Pyrex container.)
• Press down with your knuckles to create a uniform surface and to push out air. This reduces drying and allows you to see actual CO2 aeration over time.
• Let the starter develop at room temperature. It takes 6-12 hours for this sweet stiff levain to peak.
• Tangzhong
• In a small saucepan, whisk the milk and flour until blended. Cook it on med-low heat for several minutes until it's thickened, stirring frequently.
• Remove the pan from the heat and see the instructions below for melting the butter in the tangzhong if you're using a stand mixer.
• Dough Mixing and Bulk Fermentation
• These instructions are for using a stand mixer. Scroll to the end for hand-kneading instructions if you do not have a mixer.
• Add the butter in chunks to the tangzhong to melt it.
• Whisk the two eggs and then the milk into the tangzhong-butter mixture. Set aside briefly.
• In the bowl of a stand mixer, briefly whisk together the flour, sugar and salt; and then add the sweet stiff starter, separating it into 5-6 portions as you add it to the bowl.
• Now pour in the prepped wet ingredients.
• With the dough hook attachment, mix on low speed for a minute, scrape down the sides, and then mix on medium speed for about 15 minutes. As you approach the 15-minute mark, the dough will become smooth and should pass the windowpane test.
• Transfer the dough to a lightly oiled bowl, form it into a ball, flip it smooth side up, cover and let rise for 6-12 hours depending on room temperature. If you refrigerate the dough, plan for longer rise times. See the photo gallery for approximate dough expansion during the bulk fermentation.
• Shaping and Final Proof
• Prepare your pans by greasing them. You can use two standard loaf pans, or make one loaf and eight rolls in a 9" round pan like I did. Other options include: sixteen rolls in two 9" round pans, eighteen rolls in two 8" square pans, twenty-four rolls in two 9" square pans, and eighteen rolls in a 9x13" rectangular pan. Your total dough weight is about 1470g.
• Scrape the dough out onto a clean countertop. There's no need for flour. Press the dough into a rectangle, divide it and roll the pieces into balls.
• Place the dough balls in your pans, cover and let proof for 2-4 hours (more if you put the dough in the refrigerator).
• Baking*
• Preheat your oven to 350F and brush the dough with the egg-milk wash.
• Bake loaves for 45-55 minutes and rolls for 30-35 minutes. Cover with foil partway through if the bread seems to be browning excessively.
• The internal temperature when ready should be at least 190F.
• Remove the bread from the oven but not the pans, brush the top with butter while its hot, and then let cool for 10 minutes before removing from the pans.
• After the bread is completely cooled, store it in a plastic bag at room temp for a week or longer.
• *Bread baked in a glass loaf pans will need longer than metal pans.
• Instructions for kneading by hand
• Mix all of the ingredients except the softened butter in a bowl with a spatula, dough whisk and/or your hands. Let rest for 10 minutes, then transfer to your countertop and knead by hand, adding 2 Tbsp of butter at a time, kneading between butter additions until the butter is incorporated and the dough stays together. Now follow the instructions above from when you transfer the dough to a lightly oiled bowl and start the bulk fermentation.

JAPANESE SOURDOUGH HOKKAIDO MILK LOAF

Steps:

• LEVAIN:.
• Mix all and let fermentation at room temp (73F) for 12 hours.
• FINAL DOUGH:.
• Mix all until stage 3 of windowpaneovernight.
• 2. rise at room temp for 2 hours, punch down, put in fridge for overnight fermintation.
• Takeout, divide, and place in pan, fits a pullman pan or 8X4 loaf tin,and rise at room temp for about 6 hours. For a pullman pan, it should be about 80% full; for US 8x4inch pan, it should be about one inch above the edge. The dough would have tripled by then, if it can't, your kneading is not enough.
• Shape.
• To shape divide dough into three parts, roll fairly thin, eliminating any air bubbles, then fold in sides and roll (photos included) place each roll in pan, allow to rest for up to 6 hours until doubled.
• bake at 400F for 45min, brush with butter when warm.

WHOLE WHEAT SOURDOUGH HOKKAIDO MILK BREAD

Steps:

• Sweet Stiff Levain
• Mix the levain ingredients in a jar or straight-walled container with space for at least 300% growth.
• Press the starter down with your knuckles or a spatula to create a uniform surface and to push out air.
• Let the levain ripen and rise. At a temperature of 76-78°F, it typically takes up to 10-12 hours for this sweet stiff levain to peak. For my starter, I see 3-3.5 times increase in size at peak. The levain will smell sweet with only a mild tang.
• Tangzhong
• In a sauce pan set to medium heat, stir the milk and flour from the tangzhong ingredient list until blended. Cook for several minutes until it thickens, stirring regularly with a spoon or heat-resistant spatula. Let cool in the pan or, for faster results, in a new bowl. The tangzhong should reach 65°C (149°F) but I don't find I need to measure the temperature because I can see when it gelatinizes. You can prepare this the night before and refrigerate it. Ensure it's covered to prevent it from drying out.
• Final Dough Mixing and Bulk Fermentation
• In the bowl of a stand mixer, add the milk (consider holding back 10g of milk if this is the first time you're making this bread or if you skip the vital wheat gluten), egg, tangzhong, salt, sugar, diastatic malt powder and levain.
• Mix with a spatula for a few seconds and also break up the levain into many smaller pieces. Next add the flour and vital wheat gluten. I like to use my spatula to mix until there aren't any dry areas.
• Allow the flour to hydrate (fermentolyse) for 20-30 minutes.
• Mix on low speed and then medium speed until you see moderate gluten development, which may take 5-10 mins.
• Lower the mixer speed to avoid splashing, and then drizzle in the melted butter a little at a time, or alternatively add room temperature butter one pat at a time. The dough may come apart; be patient and continue to mix until it comes together before adding in more butter.
• Once all the butter has been incorporated, increase the mixer speed gradually to medium. Mix at medium until the gluten is well developed, approximately 10 mins. You can rest the dough intermittently during this time if your stand mixer heats up. You should be able to pull a windowpane but it won't be quite as thin as a white-flour windowpane because of the presence of bran in the whole wheat flour.
• This is a good time to add inclusions such as my favorite, black sesame seeds. At this point they don't interfere with the gluten development. If you add inclusions, mix until they are incorporated in the dough.
• On the counter, shape the dough into a tight ball. Place it in a bowl, cover and ferment for 2.5 to 3.5 hours at 82°F. There may be some rise visible at this stage, but don't expect the dough to inflate a lot or double in size.
• At the end of the bulk fermentation, you can immediately proceed to shaping or refrigerate the dough for about 1.5 hours to make it easier to shape. You can also retard the dough overnight, however, you may find that this increases the sourness of your bread. Keep in mind that the final proof will take longer if you chill your dough.
• Shaping and Final Proof
• Prepare your pan by greasing it or lining it with parchment paper.
• Lightly flour the top of the dough. Scrape the dough out onto a clean work surface and divide it into four pieces. I like to weigh them to have equal sized lobes.
• Shape the pieces into tight balls and allow them to rest for 5 minutes.
• Using a rolling pin, roll out each ball into a square and then letter fold it. Turn it 90 degrees and roll again to about 8" long. Letter fold again from the long sides so you have a long narrow dough. Then using a rolling pin, roll flatter, keeping the dough relatively narrow. Next roll up each long piece of dough into a tube with some tension.
• The extra letter fold makes the final rolls shorter and fatter so when they are placed in the pan, they don't touch the sides of the pan. This way the swirled ends can expand unimpeded during final proof and remain visible in the final baked bread. This shaping style is for an appearance preference and optional.
• Arrange the rolls of dough inside your lined pan, alternating the direction of the swirls. This placement allows for greater rise during proofing and baking.
• Cover and let the dough proof for 6-8 hours at a warm temperature. I proof at 82°F. You will need longer than 6-8 hours if you chilled your dough for shaping. I proof until the top of the dough comes to within 1 cm of the top edge of the pan.
• Baking
• Brush the dough with the egg-milk wash and begin preheating the oven to 350°F. Just prior to baking, brush with the egg-milk wash again.
• Bake the loaf for 50 minutes or until the internal temperature is at least 190°F, rotating as needed to get even browning. Shield your loaf if it gets brown too early in the baking process.
• After 50 minutes, lower the oven temperature to 325°F and remove the bread from the pan. Bake an additional 10 minutes with the loaf directly on the oven rack.
• When baking is complete, you can brush the top of the loaf with butter while the bread is still hot to keep the top crust soft.
• Let the bread cool about two hours before slicing. Store it wrapped in plastic or beeswax wrap. This bread can last over a week without staling.
