Super-soft Milk Bread 日本風食パン

Many years ago, when we visited Tokyo 東京, we stayed at hotels in the Asakusa area 浅草. (More recently, we've been staying at hotels in the Ginza/Tokyo station area). One of the fond memories we have of our stay at the Asakusa hotels was going to a coffee house or "Kissa-ten" 喫茶店 for breakfast and coffee. At that time, they usually offered, at a very reasonable price, choices of "morning sets" モーニングセットdesignated as  "A", "B" or "C". They consisted of some kind of egg (hard boiled or egg salad) and slightly different sides such as a mini green salad or cucumber. The foundation of the meal, and, as far as we are concerned, the best part, was a very thick slice of soft bread lightly toasted and served with butter or sometimes jam or jelly. The second cup of coffee was usually available at a steep discount which was another reason we liked breakfast at the Kissa-ten. Recently my wife came across a recipe for "Super-soft Milk Bread". In addition to being reminiscent of our favorite Kissa-ten bread, the accompanying write-up referred to it as a variation of "Hokkaido milk bread". Since I am originally from Hokkaido 北海道, that "sealed the deal". I had to make this. This is a very different recipe from our usual white bread loaf. It came out super soft, light and fluffy. It really reminded us of "Kissa-ten" toast. I sliced a very thick piece (but not as thick as some we had at kissa-ten) toasted it and slathered on the butter. Voila!

Some Japanese recipes for this type of bread include "Yu-dane" 湯種 or "Yu-kone or Yu-gone" 湯捏ね in which  a portion of flour is mixed and kneaded with hot water. Instead, this recipe pre-cooked the flour and milk into a soft paste called "tangzhong" which is the Chinese pronunciation of "Yu-dane"  湯種.  I read that this was popularized by a Chinese cookbook author Yvonne Chen as "tangzhong" which is the term that commonly appears in English-written recipes for this type of bread. This recipe came from the King Arthur website.

Ingredients
Tangzhong
3 tablespoons (43g) water
3 tablespoons (43g) whole milk
2 tablespoons (14g) King Arthur Unbleached Bread Flour


Dough
2 1/2 cups (298g) King Arthur Unbleached Bread Flour
2 tablespoons (14g) Baker's Special Dry Milk or nonfat dry milk
1/4 cup (50g) sugar
1 teaspoon salt
1 tablespoon instant yeast (This looked like too much for one loaf of bread, next time I may reduced it in half)
1/2 cup (113g) whole milk
1 large egg
4 tablespoons (57g) unsalted butter, melted

I weighed all ingredients except for the yeast and egg.

Directions

To make the tangzhong: Combine all of the ingredients in a small saucepan, and whisk until no lumps remain.

Place the saucepan over low heat and cook the mixture, whisking constantly, until it becomes thick and the whisk leaves lines on the bottom of the pan, about 3 to 5 minutes (#1 below).

Transfer the tangzhong to a small mixing bowl or measuring cup and let it cool to lukewarm.
To make the dough
Combine the tangzhong with the remaining dough ingredients, then mix and knead — by mixer or bread machine — until a smooth, elastic dough forms; this could take almost 15 minutes in a stand mixer (I used a standing mixer with a dough hook and kneaded it for 7-10 minutes).

Shape the dough into a ball, and let it rest in a lightly greased bowl, covered, for 60 to 90 minutes, until puffy but not necessarily doubled in bulk.

Gently deflate the dough and divide it into four equal pieces; if you have a scale each piece will weigh between 170g and 175g (I divided the dough in half-- I should have weighed the halves; the loaf came out uneven).

Flatten each piece of dough into a 5" x 8" rectangle, then fold the short ends in towards one another like a letter. Flatten the folded pieces into rectangles again (this time about 3" x 6") and, starting with a short end, roll them each into a 4" log. (After flattening, folding, I rolled it into two logs).

Place the logs in a row of four (in my case, two) — seam side down and side by side — in a lightly greased 9" x 5" loaf pan.

Cover the loaf and allow it to rest/rise for 40 to 50 minutes, until puffy (#2 below).

Toward the end of the rising time, preheat the oven to 350°F.

To bake the bread: Brush the loaf with milk and bake it for 30 to 35 minutes, until it's golden brown on top and a digital thermometer inserted into the center reads at least 190°F (#3 below).
Remove the loaf from the oven and cool it in the pan until you can transfer it safely to a rack to cool completely (#4).

The dough rose rather quickly (this is the reason I think I will reduce the yeast next time). After the bread completely cooled, I sliced it (#4).We have been making white bread loafs for some time using an old recipe which came with our stand mixer. Our white bread loaf is good but this one is different and may be better. It is extremely light and very close to the Japanese loaf bread we had at the Kissa-ten. We were "transported" back to Tokyo with the first bite. It had a mildly sweet flavor and the crust was nice and crunchy. We will definitely make this again for sure.

Addendum:

I doubled the amount and made two loaves. I also, decreased the yeast by half (proportionally). I also weighed the 4 portions (2 for one loaf) and they came out in equal sizes (see pictures below). This is just a note to myself so that I do not have to calculate  the ingredients' weight again.

Ingredients:

Tangzhong
86 g water
86 g whole milk
28 g King Arthur Unbleached Bread Flour

Dough
596 g King Arthur Unbleached Bread Flour
28 g  nonfat dry milk 
100 g sugar
2 teaspoon salt
1 tablespoon instant yeast
226 g whole milk
2 large egg
114 g (one stick) unsalted butter, melted

Despite halving the yeast, the dough rose and the bread came out soft and fluffy. It may have taken a little bit more time to rise but the flavor of the bread, we thought, was better.
