Komeko Shokupan (米粉食パン, rice-flour loaf)

Ingredients

Equipment Needed

• •Digital scale
• •1-kin lidded shokupan pan, about 20 x 10 x 10 cm, or an 8 1/2 by 4 1/2-inch metal loaf pan for yamagata
• •Stand mixer with paddle, or a sturdy spatula
• •Instant-read thermometer

Instructions

1. 1

   Make the yudane

   Put 60g of the rice flour in a heatproof bowl. Pour in the boiling water all at once and stir immediately until no dry flour remains and the paste turns glossy and tight. Cover the surface and let it cool until warm, at least 30 minutes. This is 湯種 (yudane, a scalded-flour starter): the boiling water swells part of the rice starch before baking, so the finished crumb holds moisture instead of drying by tomorrow.

   A straight method mixes everything at once. Yudane asks for one extra bowl, and pays you back for days.
2. 2

   Prepare the pan

   Oil a 1-kin lidded shokupan pan, about 20 x 10 x 10 cm, including the lid if you want kaku, the square loaf. For yamagata, the mountain loaf, use the same pan without the lid or use a narrow metal loaf pan. Same dough, different finish: kaku gives thin crust and tidy sandwich slices, while yamagata browns a little more and rises into a rounded crown.

3. 3

   Mix the dough

   Whisk the remaining 260g rice flour with the psyllium, sugar, yeast, and salt until evenly mixed. This matters because dry pockets of psyllium become rubbery knots once water touches them. Dissolve the mizuame in the warm water, tear the cooled yudane into pieces, and add both to the flour. Beat with a paddle for 3 minutes, or stir hard with a sturdy spatula for 4 to 5 minutes. It should look like a thick, elastic batter, not wheat dough. That's right. There is no gluten to knead, only starch and psyllium to hydrate.

4. 4

   Read the texture

   Rest the dough for 10 minutes, then beat in the rice oil. The rest lets the rice flour drink, and adding the oil after that keeps it from coating dry grains too early. The dough should fall from the spatula in slow folds and hold a soft peak. If it stands stiff and tears, beat in warm water 5g at a time. If it seems loose, wait 5 minutes before judging; psyllium is slow to show its strength.

   Different rice flours drink differently. The texture is the truth here, not the number on the measuring cup.
5. 5

   Pan the dough

   Scrape the dough into the prepared pan and smooth the top with a wet spatula. Tap the pan lightly on the counter to settle large air pockets, but don't pound it flat. Rice-flour dough rises once, and it spends its strength in that one proof, so give it an even start.

6. 6

   Proof once

   Cover the pan and proof in a warm place, about 30 to 32 C, for 35 to 55 minutes. Heat the oven to 190 C while it rises. For kaku, stop when the surface is 1 to 1.5 cm below the rim, then slide on the lid. For yamagata, let the dome reach the rim or just above it. The dough should look airy, with tiny bubbles at the surface and a gentle wobble. Do not wait for it to double. Rice flour has no gluten net to forgive overproofing, and a loaf pushed too far will sink in the oven to make its point.

7. 7

   Bake the loaf

   Bake kaku shokupan with the lid on for 40 to 45 minutes. Bake yamagata uncovered for 35 to 40 minutes, tenting loosely with foil if the top colors before the center is set. The loaf is done when the center reaches 96 to 98 C. Trust the thermometer more than the crust color; rice-flour bread browns modestly, and an underbaked center turns gummy no matter how handsome the outside looks.

   The starch must set all the way through. That is the one detail that decides whether the crumb slices cleanly or smears.
8. 8

   Cool completely

   Rap the hot pan once on a folded towel, then turn the loaf out immediately onto a rack. That small shock helps the sides release, and leaving the loaf in the pan softens the crust and can pull the walls inward. Cool at least 90 minutes before slicing. Cut too early and you make paste, then blame the rice. The rice is innocent.

9. 9

   Slice and serve

   Slice thickly with a serrated knife once the loaf is fully cool. Kaku is the one for sandwiches, especially tamago sando, while yamagata is generous for toast. Eat it plain first, so you understand the clean rice finish, then add butter if you like. Nothing hidden.

Chef Tips

• •Buy pan-yō komeko, rice flour milled for bread, from non-glutinous rice. Mizuhochikara is a good name to see on the bag. Do not use mochiko or shiratamako; those are glutinous rice flours and will give you a sticky rice cake, not shokupan. If the package lists wheat gluten, it is not this loaf.
• •The straight method, ストレート, is useful when the flour has been milled exactly for bread and the loaf will be eaten quickly. For the home oven, yudane is the better bargain. It gives softness without pretending rice is wheat.
• •Do not chase a tall proof. Wheat dough can stretch around gas; rice-flour dough cannot. Stop when the loaf is nearly at its baking height and let the oven finish the rest.
• •Cool the loaf fully before judging it. Rice starch keeps setting as it cools, and the crumb you see at 20 minutes is not the crumb you earned.

Advance Preparation

• •The yudane can be made 1 day ahead. Cover it tightly, refrigerate it, and bring it back to room temperature before mixing so it blends evenly into the dough.
• •The baked loaf is best sliced after a full cool, and even the next morning. Wrap it tightly once cool and keep it at room temperature for up to 2 days.
• •Freeze thick slices for up to 1 month. Toast from frozen or warm gently. Do not refrigerate the loaf; cold storage firms rice starch faster.
