Napolitan (Japanese ketchup spaghetti)
ナポリタン · Yokohama-style spaghetti stir-fried with ketchup, sausage and peppers
Napolitan was born in post-war Yokohama, where a hotel chef made spaghetti for occupying soldiers with what he had, and it went on to become the comfort food of Japanese coffee shops and school lunches. Soft spaghetti is stir-fried with sliced pork frankfurters, onion, green pepper and mushrooms, then coated in caramelised ketchup with a knob of butter and a shower of Parmesan. It is unashamedly sweet, tangy and child-friendly. For a vegetarian plate, swap the sausages for 150 g more mushrooms. The common mistake is just warming the ketchup: fry it in the pan first until it darkens and smells jammy, which takes away the raw sourness. Chef's tip: cook the pasta a minute past al dente, as Japanese diners do, so it soaks up the sauce.

Boiled pasta
The basic method for any dried pasta, from penne to spaghetti. A large pan of salted boiling water keeps the pasta from sticking, and you cook it only until just done, with a little bite left. Use it in salads, bakes or with any sauce.
Miso soup
Miso soup (味噌汁) is drunk every day in homes all over Japan, at breakfast as well as dinner, beside a bowl of rice. The base is dashi; this vegan version uses kombu and dried shiitake instead of bonito, which gives it a deep, rounded flavour. Silken tofu and wakame seaweed are the classic fillings. It takes ten minutes; just remember not to boil the miso. Chef's tip: add the miso at the very end and never let it boil. Boiling kills the miso's fresh, fermented aroma; Japanese cooks say the soup should only 'smile', with the surface barely trembling.
Yaki onigiriGrilled rice balls
Yaki onigiri (焼きおにぎり) are rice balls grilled until they form a crisp, toasty crust, then brushed with soy sauce glaze. They are eaten all over Japan, at izakaya, at barbecues and from the freezer section, as a snack or with miso soup. The inside stays soft and steamy while the outside crackles. Best eaten hot, straight from the pan. Chef's tip: let the shaped rice balls dry for 10 minutes before they go in the pan. A drier surface forms a better crust and won't stick, and the glaze goes on only at the end so it doesn't burn.
