Product Overview

The 'Beef and Tofu Set Meal' is a rice-complementing dish crafted with richly flavored dashi broth, combining the savory taste of beef and the delicate texture of tofu. The dashi is made using katsuobushi (bonito flakes) from枕崎 (Makurazaki) and authentic kombu kelp from Hokkaido. To finish, a premium topping called 'Hana-katsuo'—a blend of two types of matured katsuobushi known for their deep umami and richness—is added. The moment the dish is served, a delicate, aromatic dashi fragrance fills the air, stimulating the appetite and delivering a profound depth of flavor from the very first bite.

Additionally, cracking an egg into the dish midway through the meal transforms the flavor into a smoother, creamier experience while preserving the dashi’s essence. The harmonious blend of beef’s richness, tofu’s gentle taste, and the fragrant dashi creates an exceptional dining experience. This high-quality meal, unique to Yayoi-ken, adds a touch of richness to everyday dining.

For those who enjoy a lighter, rice-accompanying side, a version with domestically sourced grated yam (tororo) is also available. For customers seeking more substance, a 'small fried chicken side dish' option is offered. Customers can choose based on their mood or preference.
