Gaeng liang (peppery pumpkin and lemon basil soup)

Gaeng liang (แกงเลียง): central Thai vegetable soup with pumpkin, baby corn and lemon basil, vegan

Older cooks in Ayutthaya and the central plains make this soup for new mothers and anyone feeling run down: a cloudy broth of pounded shallot, white pepper and krachai (fingerroot), packed with pumpkin, baby corn, sponge gourd and handfuls of lemon basil. It is eaten as one of several dishes with rice at a home meal, never as a creamy starter. The everyday version pounds dried shrimp and shrimp paste into the base and seasons with fish sauce; here dried shiitake and tamari give the savouriness, so it is vegan. Chef's tip: add the lemon basil off the heat at the very end; boiled basil turns black and loses the peppery perfume the soup is named for.

Method

0/6 done
  1. Step 1: Pound 4 shallots, 1 tsp white peppercorns, 1 oz krachai (fingerroot) and ½ tsp salt in a mortar to a coarse, moist paste.

    5 min
  2. Step 2: Bring 4 ¼ cups water to the boil in a pot with the sliced 6 dried shiitake mushrooms. Stir in the paste and simmer for 2 minutes so the broth turns cloudy and peppery.

    2 min
  3. Step 3: Add 9 oz pumpkin and simmer over a medium heat until a knife slips in easily but the chunks still hold their shape, 6–8 minutes.

    8 min
  4. Step 4: Add 8 baby corn and 1 sponge gourd (luffa) and simmer until the gourd turns translucent, about 3 minutes.

    3 min
  5. Step 5: Season with 2 tbsp tamari, then taste: it should be peppery and gently savoury, not salty.

  6. Step 6: Take the pot off the heat, stir in 2 handfuls lemon basil (bai maenglak) and serve straight away with rice.

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.

BabboucheSpiced snail broth

After dark in Marrakech's great square, the babbouche stalls are recognisable by their steaming cauldrons and the toothpicks laid out by every bowl. Small land snails simmer in a dark broth of liquorice root, aniseed, thyme, caraway, bitter orange peel, chilli and a bundle of herbs that sellers say has fifteen ingredients, believed to soothe the stomach and warm you on a cold night. You pick the snails out with a toothpick, then drink the peppery, herbal, faintly sweet broth. At home, buy live snails sold for cooking, already purged by a reputable seller, discard any with broken shells or that do not move or retract when touched, and cook them through for at least 45 minutes. Chef's tip: keep the spices in a muslin bag; the broth stays clear and you avoid crunching on seeds.
