LONDON (Kyodo) An Osaka woman and her British husband are combining traditional Japanese ingredients with chocolate to create some unique offerings to tempt sweet-toothed Britons.

For the last five years, chefs Suzue and William Curley have been trying out different foods from Japan and mixing them with chocolate to produce a variety of treats at their patisserie in Richmond, southwest London.

Among the Japanese ingredients they have used in their chocolates are black vinegar, green tea, toasted sesame seeds, wasabi and the citrus fruit "yuzu." They also use Sichuan pepper.
