TL;DR

FamilyMart developers reveal the meticulous process of creating their 'Uma-Juwa' Salt Butter Bread, featuring Lorraine rock salt and innovative production techniques for ham, cheese, chocolate, and melon bread varieties.

On Tuesday, June 2nd, FamilyMart released three types of salt bread under the name 'Uma-Juwa~! Salt Butter Bread'!

Salt bread has now surpassed 8,000 listed stores on review sites nationwide, becoming one of the 'protagonists' of Japanese bread culture. Following the popularity of last year's 'Salty Sweets,' we decided to create 'Salt Butter Bread.'

🔷Development Points🔶

What we pursued was a sinful 'juicy' (juwa~) sensation. The life of salt butter bread is, above all, the contrast between 'buttery feel' and 'saltiness.' This time, we intentionally used 'Salted Margarine with Fermented Butter' as an ingredient. By using fermented butter, you can enjoy deep richness and a unique refreshing acidity and aroma.

As an accent to the fermented butter margarine, we chose 'Lorraine Rock Salt' from among many salts. This rock salt from the Lorraine region in northeastern France is characterized by a mellow saltiness without any harshness compared to other salts. We were particular about the salt so it would suit both sweet and savory breads.

🔷Product Specifics🔶

■Salt Butter Ham & Cheese Bread

First, the ingredients. We used cheese cream blended with Gouda cheese, selecting materials that wouldn't spoil the flavor of the salt butter bread.

Next, the production method. This is packed with points of obsession! If you put smooth cheese cream in before baking, the cheese burns off...

But if you put it in after baking, it overflows from the bread.

To solve this 'cheese cream overflow,' we manufactured a 'custom-made injection nozzle'!! It's a product designed so you can fully enjoy the taste of the cheese cream.

■Salt Butter Chocolate Bread

For this chocolate bread, we tried adjusting the chocolate cream to match the salt butter bread and arrived at this chocolate cream. It has a stronger flavor than regular cream, making it a perfect match for salt butter bread. Furthermore, to increase the chocolate feel compared to the 'Salt Butter Bread (Chocolate Cream)' released in last year's Salty Sweets project, we changed it to use chocolate chips.

Additionally, following last year's response, the bicolor (two-tone) visual was something we couldn't leave out. We expressed the bicolor look by laminating chocolate-flavored French bread dough and Danish dough.

■Salt Butter Melon Bread

Finally, we created a forbidden combination: 'Salt Butter Bread x Melon Bread.' To make you feel the 'juicy' sensation even more, which is the focus this time, we used Danish dough for the base.

By adding a lattice pattern to the surface, we gave it a look that combines melon bread and salt butter bread.

🔷Closing🔶

In developing this series, we conducted repeated market research, focusing on popular salt butter bread shops. Please try FamilyMart's 'Uma-Juwa~! Salt Butter Bread' 🍞
