Nori tsukudani

Nori no tsukudani (海苔の佃煮): stale nori sheets simmered into a dark, glossy seaweed paste for rice

When a pack of nori loses its crispness, Japanese cooks turn it into nori tsukudani, the jet-black, jammy seaweed paste sold in jars as "gohan desu yo" and spread over the rice in bento boxes up and down the country. It tastes of the sea, soy and a gentle sweetness. The common mistake is walking away: once the water has gone the paste catches on the bottom within a minute. Chef's tip: soak the torn nori before you heat it, so it melts into a smooth paste instead of leaving chewy shreds.

Method

0/4 done
  1. Step 1: Tear 5 nori sheets into small pieces into a small saucepan, pour over ¾ cup water and leave for 5 minutes, until the pieces are soft and floppy.

    5 min
  2. Step 2: Add 2 ½ tbsp soy sauce, 2 tbsp mirin and 1 tbsp sugar. Mirin carries a little alcohol that cooks away; use the swap for an alcohol-free paste.

  3. Step 3: Simmer over a medium-low heat, stirring and mashing with a wooden spoon, for 8–10 minutes, until the nori has melted into a thick paste and a spoon dragged across the pan leaves a clear line.

    10 min
  4. Step 4: Stir in 1 tsp toasted sesame seeds, if using. Cool, then keep in a jar in the fridge for up to 1 week. Spread a thin layer over bento rice.

Okonomiyaki

Okonomiyaki (お好み焼き, 'grilled as you like it') is the pride of Osaka, where it's cooked on hot iron griddles in lively restaurants. Finely shredded cabbage is folded into a light batter with egg and spring onion, then fried into a thick, soft pancake with a crisp outside. It's painted with a fruity brown sauce and zigzagged with mayonnaise. Bonito flakes are usual on top; this vegetarian version uses seaweed flakes and pickled ginger instead. Chef's tip: don't press the pancake down with your spatula while it cooks. Osaka cooks leave it alone so the cabbage steams inside and stays light and fluffy; pressing squeezes out the air.

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.

Agedashi tofu

Agedashi tofu (揚げ出し豆腐) is a classic izakaya dish eaten all over Japan: cubes of soft tofu dusted in potato starch, fried until they form a thin, crisp shell, then bathed in a hot, savoury broth. The coating turns silky as it soaks up the sauce while the tofu inside stays creamy. Usually topped with bonito flakes; here it's grated daikon, ginger and spring onion with a kombu-shiitake broth instead. Chef's tip: coat the tofu in starch right before it goes into the oil, not ahead of time; if it sits, the starch turns damp and the coating fries up gummy instead of crisp.
