What You Need to Know
Hoshigaki involves sequential enzymatic breakdown of tannins (proanthocyanidins) and conversion of sucrose to reducing sugars (fructose/glucose) through daily hand-massage during 4-6 week drying. The process develops surface fructification and Maillard reaction products.
Prized as a luxury confectionery item and gift, used in wagashi (traditional sweets) and as natural sweetener in upscale cuisine.
