White Mausu Peanut Rayu

White Mausu is a boutique Irish condiment brand that achieved cult status with its signature Peanut Rayu, a fusion of Japanese, Chinese, and Korean flavors. The brand was founded in 2017 by Katie Sanderson and Jasper O'Connor, who drew inspiration from their culinary backgrounds and travels to create unique, texture-rich sauces.

Everything is manufactured in Ireland, specifically originating from the producers' base in Galway. The brand emphasizes high-quality ingredients and small-batch production. As of 2026, White Mausu remains an independently owned company headquartered in Dublin, Ireland, continuing to expand its presence across the UK and European specialty food markets without being absorbed by a global food conglomerate.
