A blend of bancha tea, which has an astringent, robust, grassy and slightly dry flavor, and toasted rice, which mellows the flavor, Genmaicha was originally created by Japanese farmers unable to afford regular bancha. Green tea brewing basics: Put 1 tsp. of tea in strainer, then place in cup. Add 8 oz. of water slightly cooled from a boil and steep for 3-4 minutes. Feel free to adjust to your preference.
