Teriyaki Glazed Duck Breast, Sesame Fondant Sweet Potato, Burnt Spring Onion Emulsion by Mervyn Desir, Whitbread

Founded in 1804, Mizkan’s origins were closely connected to sake production. The company developed vinegar from sake lees; a by-product of the sake brewing process, at a time when nigiri sushi was booming in Edo, modern-day Tokyo.
That heritage continued to underpin Mizkan’s focus on authentic Japanese ingredients and Japanese-inspired flavours. The company’s presentation highlighted its considerable presence in Japan, where it described itself as number one in both retail and foodservice.
