BettarazukeSweet koji-cured daikon
Every 19 and 20 October, the lanes around Takarada Ebisu Shrine in Nihonbashi fill with stalls for the Bettara-ichi, Tokyo's old pickle fair, where vendors hold up whole daikon dripping with rice koji and passers-by try not to get 'bettari', sticky. The pickle has been an Edo favourite since the 1700s: daikon salted, then buried in amazake, the sweet porridge that koji makes from rice. It tastes mild, sweet and fresh, with a clean crunch and a faint fermented, sake-lees perfume, which makes it a favourite with children and a pause between salty dishes. Bettarazuke is low in salt and acid, so it lives in the fridge from start to finish. The common mistake is adding the daikon while the amazake is still warm: it cooks the surface and softens the crunch, so cool it fully. It is ready when the daikon is translucent at the edges, juicy, and the koji coating tastes sweet with a light tang. Chef's tip: make the amazake in a rice cooker on keep-warm with the lid ajar and a cloth over it, so it holds about 60 °C; a thermometer helps the first time.
