A New Standard in Mayonnaise: Heat-Resistant and Delicious

In a culinary landscape where taste and versatility are paramount, St. Cousair Co., based in Nagano, has made significant strides by collaborating with Kenko Mayonnaise Co. from Tokyo to introduce an original mayonnaise sauce specifically designed to withstand heat during cooking. This exciting development aligns with the recent renewal of St. Cousair's popular Iburigakko Tartar Sauce, known for its unique flavors and textures.

Background of Development

The initiative to create the mayonnaise sauce stemmed from the need for a product that could endure high-temperature cooking processes, such as煮込み (nikomi, or simmering) and高温殺菌 (high-temperature sterilization), without compromising on taste. As St. Cousair sought to enhance the natural flavors in their products, they enlisted the expertise of Kenko Mayonnaise, a leader in the food industry that supports culinary professionals.

Features of the Original Mayonnaise Sauce

The newly crafted mayonnaise sauce boasts a rich, mild flavor with a pronounced egg profile. Designed to withstand extensive heating, the sauce is also compatible with post-bottling sterilization processes. In a bid to maintain authenticity, the development focused on minimizing additives and excluding umami seasoners and emulsifiers, thus allowing the original ingredients to shine. This careful formulation enhances the flavor and texture of the Iburigakko, ensuring a harmonious taste experience.

The Development Story

The journey of creating this mayonnaise was not without challenges. Throughout approximately a year of prototypes and testing, the teams at both companies encountered issues with separation and flavor retention. By fostering close communication and collaboration, they navigated these hurdles to produce a stable and delicious product. The process involved extensive validation in St. Cousair's laboratory, augmented by video calls to monitor separation issues, which ultimately resulted in a mayonnaise that balances taste and heat resistance. A representative from St. Cousair expressed immense gratitude towards Kenko Mayonnaise for their unwavering support and expertise throughout this journey.

Future Plans

Looking ahead, St. Cousair aims to further develop products utilizing their proprietary mayonnaise sauce, in line with their commitment to relentlessly pursue culinary excellence. The company embraces the concept of “Food SPA,” overseeing every phase from raw material procurement to production and sales, while ensuring they extract the maximum potential from every ingredient.
