Method

Cook the pasta in a saucepan of boiling salted water for 10–12 minutes, then drain, reserving a cup of the cooking water.

Meanwhile, heat the oil in a frying pan and fry the shallots for 5 minutes until soft but not coloured. Add the greens and a splash of the pasta water, cover and cook for 2–3 minutes.

Melt the butter with the miso paste and blend with 150ml (2/3 cup) of the pasta water until smooth. Add to the drained pasta with the greens. Serve with lots of cracked black pepper.

Cook's notes

Save a good cup of the starchy pasta water before you drain — it's what loosens the miso butter into a glossy sauce.
Do it the way I did on the show: put the butter and miso in a bowl and work in the hot pasta water until completely smooth before it goes near the pasta — no salty pockets of undissolved paste.
Miso is salty, so go easy salting the pasta water and taste before adding any more at the end.
Soften the shallots gently without letting them colour — you want them sweet and mellow, not browned and bitter under the delicate sauce.
Don't skimp on the cracked black pepper at the end; it cuts through the buttery miso beautifully.

Serve with A poached or fried egg on top makes it more of a meal, and a handful of toasted sesame seeds adds crunch. A crisp, dry white or a light Japanese beer suits the savoury notes.

Make ahead & storage Best served straight away while the sauce is silky — it stiffens as it cools. If you do have leftovers, reheat gently in a pan with a splash of water to bring the sauce back.
