Mozuku-zu

Seaweed in sweet vinegar

Mozuku-zu (もずく酢): Okinawan mozuku seaweed in a light sweet vinegar with grated ginger

In Okinawa, where most of Japan's mozuku is farmed, a small bowl of mozuku-zu starts many a home supper and izakaya meal, especially in the hot months. The fine, slippery strands of seaweed are rinsed of their salt and served cold in a gentle dressing of rice vinegar, a little sugar and soy, topped with grated ginger, so it tastes clean, sour and of the sea. Shop versions often use bonito dashi; this one uses kombu dashi, so it is vegan. It is very light, with less than 1 g of protein a portion, so it belongs alongside a tofu dish and rice rather than as a main. The most common mistake is not rinsing salted mozuku enough: it needs two or three changes of water or the dish turns harsh. Chef's tip: chill the dressing and the bowls well; mozuku-zu should be served icy cold.

Method

0/4 done
  1. Step 1: Put 7 oz salted mozuku seaweed in a bowl of cold water, swish it around and drain. Repeat two or three times, until a strand tastes only mildly salty. Drain well.

  2. Step 2: Stir ¼ cup kombu dashi, ¼ cup rice vinegar, 1 tbsp sugar and 2 tsp light soy sauce together until the sugar dissolves. Chill for 10 minutes if you have time.

  3. Step 3: Cut the mozuku into 5 cm lengths with scissors if the strands are very long, then divide between small chilled bowls with ½ cucumber, if using.

  4. Step 4: Pour the dressing over and top each bowl with a little ¾ in fresh ginger. Serve cold.

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.

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.

TashmijabiMashed potatoes with stretchy cheese

Potatoes grow well in the cold valleys of Svaneti, and tashmijabi is how families around Mestia turn them into a feast dish: they are mashed hot, then beaten with handfuls of young sulguni until the purée becomes glossy and stretches from the spoon in long strands. It is served with grilled meat, kubdari or simply with pickles and Svan salt. A common mistake is letting the potatoes cool before adding the cheese; they must be piping hot for the cheese to melt and stretch. Chef's tip: keep the pan on a low heat while you beat, and use a firm wooden spoon. Most sulguni uses animal rennet; choose a vegetarian one or use mozzarella.
