Mochi simply means ‘rice cake’ – and beyond the sweet, chewy versions you might know, it can also be made from sticky rice lightly pounded by hand, as it is in the mountains of central Japan. This rustic style, traditionally grilled over charcoal after the autumn harvest, is brushed with a sweet-salty miso sauce; I especially love it with walnuts, toasted until the rice is crisp and nutty at the edges.
You’ll likely have a little walnut miso left over – a very good thing, as it’s wonderful spooned onto just about anything.
Method:
Put the rice in a sieve and wash a few times to remove the excess starch. Drain and tip into a saucepan. Add the water and bring to a simmer. Cover, reduce the heat to the lowest setting and simmer for 15–17 minutes until the rice is tender. Keep covered and leave to steam off the heat for a further 10 minutes. You can also use a rice cooker for this.
Lightly pound the rice a few times using a suribachi or mortar and pestle (or get creative if you don’t have one – the end of a rolling pin and a bowl, for example). It should be a sort of sticky mass but with still visible rice grains.
With wet hands, roll the rice into 6 balls, then push bamboo skewers or popsicle sticks into the balls and shape into flattened ovals around the sticks (they are meant to look like waraji sandals).
To make the walnut miso, grind the walnuts – a suribachi does this perfectly, or use a mortar and pestle. Make this as chunky or smooth as you like.
Add the miso and brown sugar and about 1 tablespoon water to loosen the mixture so it is easily spreadable. Taste: it should be delicious but you can adjust the sweetness (sugar) and saltiness (water or miso).
Grill both sides of the rice cakes until nicely toasted. Spread with a layer of walnut miso, sprinkle with sesame seeds and serve immediately.
