Kiam chye ark (salted vegetable duck soup)

Duck simmered with salted mustard greens, tomatoes, tamarind and sour plums into a tangy soup

Kiam chye ark is the soup Penang Nyonya families make around Chinese New Year, traditionally to use up roast duck from the reunion dinner; its sour, salty broth is said to settle the stomach after the feasting. This version starts from a fresh jointed duck. Duck is simmered with salted mustard greens (kiam chye), tomatoes, tamarind skins, preserved sour plums and a little ginger until the meat is falling-apart tender and the broth is clear, tangy and savoury. Serve it piping hot with plain rice and a dish of sliced chilli in soy. Chef's tip: soak and taste the salted greens first; some brands are fiercely salty and need a second soak.

Method

0/6 done
  1. Step 1: Taste a piece of soaked 10 ½ oz salted mustard greens (kiam chye); if it is still very salty, soak it in fresh water for another 15 minutes and squeeze dry.

    5 min
  2. Step 2: Put 1 duck in a large pot of cold water, bring to the boil and blanch for 5 minutes until the scum rises. Drain, rinse the duck and clean the pot.

    12 min
  3. Step 3: Return the duck to the pot with 10 ½ cups water, 1 ⅜ oz fresh ginger, 1 bulb garlic and 1 tsp white peppercorns and bring to the boil over a high heat, skimming off any foam.

    10 min
  4. Step 4: Add the salted greens, 4 tomatoes, 4 preserved sour plums and 2 tbsp dried tamarind slices (asam keping) or tamarind paste, lower the heat and simmer, partly covered, for 1½–2 hours, until the duck is very tender and comes away from the bone easily.

    105 min
  5. Step 5: Skim off as much fat as you can from the surface. Common mistake: leaving it on; the soup then tastes heavy instead of sharp and clean.

    3 min
  6. Step 6: Taste and add ½ tsp salt only if needed (the greens are salty). Serve hot in bowls with 2 red chillies and 1 handful fresh coriander.

Tiyula itumBlack beef soup

Tiyula itum, 'black soup', is the pride of the Tausug people of Sulu in the far south of the Philippines, cooked for weddings, Eid celebrations and when guests come home. Beef (it is a halal, pork-free dish) is simmered with ginger, lemongrass and turmeric, then darkened with pamapa itum, a paste of grated coconut toasted until almost black and pounded with spices. The broth looks dramatic but tastes smoky, earthy and gently peppery, with heat from chillies. Serve it with plain rice. Chef's tip: toast the coconut slowly, stirring all the time, until it is very dark brown but not ashy; burnt-to-ash coconut tastes bitter and ruins the soup.

Ful nabitSprouted fava bean soup

Sprouted beans are ladled out with their cooking liquor in Cairo homes when the weather turns cold or someone is feeling run down, and Egyptians swear by the broth as a pick-me-up. The beans are soaked and left to sprout for a few days, then simmered with onion, garlic and cumin into a light, earthy soup that is sharpened at the table with plenty of lemon. You can eat the beans with a spoon or pop them from their skins. Allow 3 to 4 days for sprouting, although the hands-on work is only about 20 minutes. People with G6PD deficiency (favism) must not eat fava beans. Chef's tip: stop the sprouting when the shoots are about 1 cm long; longer sprouts taste grassy and bitter.

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.
