金箔
Gold leaf (as well as other metal leaf such as vark) is sometimes used to decorate food or drink, typically to promote a perception of luxury and high value; however, it is flavorless. It is occasionally found in desserts and confectionery, including chocolates, honey and "mithai". In India it may be used effectively as a garnish, with thin sheets placed on a main dish, especially on festive occasions. When used as an additive to food, gold has the E-number E175. A traditional (centuries old) artisan variety of green tea contains pieces of gold leaf; 99% of this kind of tea is produced in Kanazawa, Japan, a historic city for samurai craftsmanship. The city is also home to a gold leaf museum, Kanazawa Yasue Gold Leaf Museum.
