Amazake — sweet fermented rice drink
A thick, warm, naturally sweet drink made from rice and kōji (rice inoculated with ferment) left to soften overnight. Non-alcoholic, sweet as rice milk: the monks' “sweet comfort.”

You seek sweetness? Do not go far to find it: it already sleeps in the rice grain. Join the cooked rice to the kōji, keep it warm all night as one tends an ember, and by morning the rice has turned to honey without any bee involved. Drink a warm bowl before the long winter sitting: it warms the hands and soothes the belly. Nature gives sugar to those who know how to wait.
- •Cooked rice — one bowl (starch to transform)
- •Kōji (rice inoculated with ferment) — same volume (natural sweetening agent)
- •Hot water — as needed for texture (dilution)
- •A pinch of salt — tiny (balance)
Amazake — sweet fermented rice drink
A thick, warm, naturally sweet drink made from rice and kōji (rice inoculated with ferment) left to soften overnight. Non-alcoholic, sweet as rice milk: the monks' “sweet comfort.”
Why this dish? Without cane sugar or abundant honey, the monastery's sweetness came from the rice itself: kōji transforms starch into a sweet, non-alcoholic nectar, comforting energy for long hours of zazen and the winters of Echizen where Dōgen founded Eihei-ji.

Ingredients (period version)
- Cooked rice — one bowl (starch to transform)
- Kōji (rice inoculated with ferment) — same volume (natural sweetening agent)
- Hot water — as needed for texture (dilution)
- A pinch of salt — tiny (balance)
Ingredients
- Cooked short-grain rice — 200 g (base)
- Rice kōji (kome-kōji) — 200 g (sweetening ferment)
- Warm water (60 °C) — 400 ml (dilution)
- Salt — 1 pinch (balance)
Method
- Mix the cooked rice, crumbled kōji, and warm water (never boiling, below 60 °C, or the ferment dies).
- Maintain the mixture at about 55–60 °C for 8–10 hours (yogurt maker, thermos, or turned-off oven with pilot light).
- Taste: when clearly sweet, it is ready.
- Blend or leave as is depending on desired texture, add a pinch of salt.
- Thin with hot water and serve warm, or chilled in summer.
How it was made : Amazake “of one night” (ichiya-zake) was prepared by keeping the mixture warm near the hearth. Rich in sugars and enzymes, it was drunk as a restorative; in monasteries, it was one of the rare sources of sweetness without resorting to sugar commerce, which was expensive.
The contemporary twist : Blended chilled with a little grated ginger and matcha, amazake becomes a trendy monk “smoothie” without added sugar.
