Shio koji

Shio koji is an old Tohoku pickling medium that swept Japanese home kitchens in the 2010s and never left. Rice koji, the grains cultured with the mould that also makes miso and sake, is rubbed with salt, covered with water and left on the counter for a week. Its enzymes break down starch and protein, so the result is a pale, porridge-like seasoning that tastes salty, mildly sweet and deeply savoury, with a fruity, sake-like scent. Use it all year in place of salt: rub it over chicken, pork or fish (about 10% of the weight) the night before grilling, toss it with vegetables for a quick overnight pickle, or stir it into dressings and soups. The common mistake is too little water: the grains must stay just covered, or the top dries and can grow mould. Stir once a day with a clean spoon and top up with a little water if needed. It is ready when the grains crush easily between your fingers, the mixture is thick and creamy, and it smells sweet rather than raw. A faint alcohol smell is normal. Chef's tip: blend the finished shio koji smooth with a stick blender; it spreads more evenly on meat and won't burn in spots.

Temae miso

Temae miso means 'my own miso', and the phrase also means bragging about your own work, because every family thinks theirs is the best. Across rural Japan the cold months of January and February are miso-making season: the low temperatures let the mash settle in slowly before summer's warmth speeds up the fermentation. Dried soybeans are soaked, simmered until soft, mashed, mixed with rice koji and salt, then packed tightly into a crock under a salt cap and a weight. By autumn it has turned from pale beige to reddish brown, sweet-salty and rich, with a rounder, fruitier flavour than shop miso. The salt, about 12% of the finished weight, is what keeps it safe, so measure it rather than guessing. The common mistake is leaving air pockets when packing, which is where mould grows; throw the mash into the container in balls and press each one down hard. It is ready when it smells sweet and savoury like soy sauce, tastes well-balanced rather than raw and floury, and dark liquid (tamari) has pooled on top. Chef's tip: make it with friends; a kilo of beans is a lot of mashing, and the batch tastes better for the company.

Bettarazuke

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.
