A book fan email list I subscribe to has been having a huge tea discussion. Someone posted that most Japanese/sushi restaurants serve tea made with loose green tea that has roasted rice in it, and she'd searched for years to find it available retail. I've always loved the green tea I've had in Japanese restaurants here in Boston, and nothing I've made at home from commercial supermarket brands has been quite the same.
Does anyone know where I can find it around here? I'm in Cambridge. I know about the local markets in Union Square and and Medford, but I wouldn't know what to look/ask for.
