Salt Bread (Japanese Shio Pan)
Forget the Croissant: Why Japanese Shio Pan is Your Next Obsession
If you haven't experienced the magic that is Shio Pan, you are missing out on one of the most perfectly engineered comfort foods in the bakery world. Literally "salt bread" in Japanese, this humble, crescent-shaped roll has a cult following—and for good reason! It’s the ultimate marriage of simplicity and decadent technique.
The Shio Pan, or "Salt Bread," is the definition of a culinary success story rooted in brilliant simplicity. What began as a local specialty in a relatively quiet corner of Japan has transformed into a continental phenomenon, even finding a second life as the equally beloved Sogeum-ppang (소금빵) in South Korea.
How did a simple butter roll with salt become a trans-Pacific bakery staple? It comes down to a perfect origin story and an irresistible formula that transcends cultural palates.
The Origins of Shio Pan and the "Frying" Butter Phenomenon
The story of the Shio Pan begins in the early 2000s, generally credited to Pain Maison, a bakery in the Ehime Prefecture on Shikoku Island.
The intent was beautifully straightforward: to create a bread that was simple, affordable, and deeply satisfying. Bakers took the soft, enriched dough, rolled a stick of cold butter inside, and topped it with coarse sea salt.
Here's where the magic happens: as the roll bakes, this inner core of butter melts out onto the baking sheet, essentially "frying" the bottom of the roll. The result is a crispy, golden-brown, irresistibly buttery crust on the bottom with a delicate, fluffy, and chewy crumb on the inside. This textural contrast—the crunch of the base against the tender interior—is what makes Shio Pan legendary and why it is perfectly positioned for modern Asian tastes.
A Symphony of Savory and Sweet
The final touch is, of course, the course salt. Just before baking, the rolls are sprayed with water and sprinkled with coarse, sea salt such as pretzel salt. This gives each bite a brilliant, surprising pop of savory saltiness that cuts through the rich butter and mild sweetness of the bread.
It’s the beautiful balance of flavor—rich butter, soft bread, a hint of sweet, and a punch of salt—that makes Shio Pan universally beloved. It's a fantastic pairing for specialty coffee, a perfect afternoon snack, or just an excuse to enjoy a piece of perfectly baked simplicity. Trust me, once you try that crunchy, buttery base, you'll understand why this "salt bread" has taken the bakery world by storm!
Crossing the Sea: The Korean Sogeum-ppang Craze
In recent years, this "salt bread" has experienced an explosive second wave of popularity in South Korea, where it is known as Sogeum-ppang (소금빵). The speed and intensity of the Korean trend, particularly among younger generations and on social media, have been remarkable.
There are a few key reasons why Sogeum-ppang resonated so powerfully with the Korean palate and modern cafe culture:
The Ultimate Flavor Balance
Korean cuisine highly values the concept of ** 단짠 (dan-jjan)**, or the perfect balance of sweet (단) and salty (짠). Shio Pan delivers this in a uniquely delicious way. The fluffy, mildly sweet dough and rich butter are instantly and intensely balanced by the sharp, crunchy burst of sea salt flakes on top. It’s a clean, addictive flavor profile.
The Cafe Culture Companion
South Korea’s vibrant and competitive cafe scene is constantly seeking new, photogenic, and satisfying pastries to pair with specialty coffee. The Sogeum-ppang, with its beautiful crescent shape and golden, glistening crust, is a natural fit. It’s light enough to be a snack but rich enough to feel like a treat, making it the perfect accompaniment to a cold brew or a latte.
Culinary Customization and Innovation
Korean bakeries took the Japanese original and ran with it, adapting it to local tastes and trends. While the classic roll remains supreme, the Sogeum-ppang has become a canvas for innovation:
Fillings: Think garlic-cream cheese, truffle butter, or even sweet fillings like red bean or condensed milk.
Toppings: Basil, chives, different varieties of specialty salt—the variations are endless, keeping the trend fresh and exciting.
From a local specialty in Shikoku to the must-have item in a Seoul cafe, the journey of the Shio Pan/Sogeum-ppang is a delicious reminder that sometimes, the simplest ideas—perfectly executed—can be the biggest global hits. It is a true trans-Pacific treat.
What Exactly is Tangzhong?
Tangzhong is an Asian technique—often referred to as a "water roux" or "starter"—that originated in China, borrowing from the similar Japanese yudane method. It is the practice of pre-cooking a small portion of the flour and liquid from a bread recipe until it forms a thick, gelatinous paste. This cooked paste is then allowed to cool and is incorporated into the main bread dough along with the rest of the ingredients.
Traditional Shio Pan is already delicious, but like many enriched rolls, it can be prone to drying out quickly. This is where the Tangzhong method rides in like a fluffy, doughy superhero.
As we discussed, Tangzhong pre-cooks a portion of the flour and liquid, enabling the flour's starches to absorb and trap a massive amount of moisture. When applied to Shio Pan dough, this simple step offers three game-changing benefits:
Next-Level Internal Fluffiness
Shio Pan needs to be soft to contrast with that crispy, buttery shell. Tangzhong ensures the final crumb is exceptionally moist, tender, and light-as-air. The higher hydration allowed by the water roux creates a finer, smoother, and more pliable dough, which translates directly to a more pillow-soft interior.
Enhanced Shelf Life (The Anti-Staling Effect)
If you've ever had a fresh Shio Pan, you know it's best eaten warm, right out of the oven. But with Tangzhong, the dough retains its moisture much longer, dramatically extending the roll's shelf life. Your rolls stay soft and fresh for days, not just hours!
The Science Behind the Softness
The impact of this simple pre-cooking step is nothing short of revolutionary, thanks to a process called starch gelatinization:
When flour and liquid (typically water or milk) are heated to around 149∘F (65∘C), the starches in the flour swell up and absorb the liquid. Crucially, the flour can absorb twice as much hot liquid as it can cold liquid. By incorporating this gelatinized paste into the dough, you are adding a significant amount of water that is already "locked up" by the flour's starches.
This allows you to increase the overall hydration of your bread dough without making it sticky, slack, or difficult to handle. The starches hold onto this moisture during the kneading, rising, and baking process. This higher moisture content is what makes the finished bread incredibly soft and, most importantly, highly resistant to staling, giving your loaf an extended, beautiful freshness.
The result is a simple, humble roll that manages to be airy, rich, savory, and sweet all at once. The Tangzhong ensures that beautiful interior remains soft for days, perfectly complementing that irresistible, crunchy, butter-fried base.

INSTRUCTIONS
Make Tangzhong Starter
In a small sauce pot, add in the flour, milk, water and whisk to combine until smooth and lump free.
Turn the heat to medium-low and cook for about 2-3 minutes, mixing with your whisk or rubber spatula the entire time. As it starts to thicken, mix constantly until everything is cooked and thickened. When done, the mixture should be very thick like slime. Pour the mixture into a bowl, cover the surface with plastic wrap and cool in the fridge to cool completely before using. This can also be made the day before.
Make Dough
In a stand mixer bowl attached with a dough hook, add in the warm milk active dry yeast, and the 10g of sugar, mix until the everything is combined. Let the mixture sit in the bowl for about 5 minutes to bloom the yeast. Then add in the egg and the cooled down starter and mix to combine. Add in the flour, remaining sugar, and salt. Mix everything together on low speed for a few minutes until they are evenly combined and you end up with a shaggy and tackydough.
Add in the soft butter and knead for about 10 minutes. Adding in a little bit more flour if needed if the dough looks a bit too sticky. After 10 minutes, the dough should be smooth and elastic.
Shape the dough into a tight ball. Place the dough into a large bowl greased with baking spray. Cover with a plastic wrap or with a kitchen towel and let it rise in a warm location for about an hour to an hour and a half or until it has doubled in size.
Once proofed, divide the dough into 65-70 grams each. Roll into tight balls and cover and rest for 15 minutes.
Shaping, Proofing, & Baking:
Roll out the ball into a cone shape thats about 6 inches long. Then using a rolling pin, roll out the fat part of the dough flat. Then gently roll and stretch the dough down until you reach the end of the dough. It will be like croissant shaping.
Place the chilled 10g salted butter piece on the edge of the fatter side of the rolled dough. Then roll up the dough like a croissant. Try to keep everything centered when rolling up the dough.
Lightly spray your two baking sheets with baking spray. Then lay 7-6 salt bread onto each baking sheet and spray each salt bread with water using a spray bottle. Proof in a warm spot like your oven with boiling water underneath for steam (you will have to remove this pot when you are ready to bake). Proof for 1 hour or until doubled in size.
Generously spray each salt bread with water and lightly sprinkle with pretzel salt on top.
Bake at 400F for 12 minutes and then lower the temperature down to 375F and bake for another 10 minutes until golden brown all around and on the bottom.
Take out of the oven and brush with melted butter for a shiny appearance.
Serve immediately and enjoy!
