Wagashi Nerikiri Red Bean Advanced Variations
Japan — red bean paste confectionery tradition since Heian period; Kyoto refinement peak
Beyond standard nerikiri, advanced Japanese wagashi technique involves multiple bean paste varieties and their distinct applications. Koshian (smooth red bean paste, strained): silky smooth, used in premium namagashi where texture refinement is paramount. Tsubuan (chunky red bean): whole beans partially crushed, retaining texture — for dorayaki, daifuku. Shiro-an (white bean paste): from white kidney beans or lima beans — base for colored nerikiri, lighter flavor than koshian. Kinton (mashed sweet potato or chestnut): for seasonal variations. The Kyoto wagashi tradition classifies bean paste quality with the same precision as French haute cuisine classifies stocks.
