COSAJI DINING 9BAN, a Western-style dining establishment in Kakogawa City, Hyogo Prefecture, operated by L8 LLC (Kasai City) and managed by owner Mayuko Yoshitome, has officially launched its 'Ultimate Gateau Chocolat' to coincide with its grand opening on May 9, 2026.
Crafted without any flour and using only four strictly selected ingredients, this dessert boasts overwhelming richness and a melt-in-the-mouth texture. It is proudly introduced to the community as the 'self-proclaimed densest gateau chocolat in Kakogawa.'
### Three Commitments to Being 'The Densest in Kakogawa'
1. **Zero Flour (Gluten-Free) and Maximized Cacao Purity** Unlike typical confectionery, this cake uses no wheat flour or cocoa powder. It consists solely of four ingredients: premium 72% cacao chocolate, unsalted butter, fresh eggs, and granulated sugar, allowing the powerful aroma and richness of the cacao to shine through.
2. **Smooth Texture through Precise Temperature Control and High-Speed Emulsification** The simple ingredients demand high-level craftsmanship. By combining the fats of chocolate and butter with the moisture of room-temperature eggs and stirring at ultra-high speed under precise temperature control, a 'perfect emulsion' state is created, resulting in a silk-like texture.
3. **The 13-Minute Miracle: Two Textures Depending on Temperature** Baked at 180°C for only 13 to 15 minutes, the cake features a crisp surface and a molten, lava-like interior. When chilled in the refrigerator, it transforms into a dense, heavy texture similar to premium raw chocolate (ganache), offering two distinct experiences in one cake.
