Back in the day when tea was too expensive for your average Japanese peasant, they'd mix it with toasted rice to make it go further. From such humble beginnings has grown a tea that in today's Japan is celebrated in its own right as Genmaicha tea or, to its friends, Popcorn tea. The British equivalent would probably be something like bubble & squeak, although obviously not recommended for use in teapots. Taste: Green tea with a popcorny, almost nutty undertone. Try it: Pure & unadorned, unless you have a really sweet tooth. Good if you're feeling: In need of a treat. As indulgent as a cinema ticket, but without the violence & naughty language, this sweet green tea will lift your spirits
