Tomato rasam

Tamil Nadu's thin, peppery tomato and tamarind soup with garlic and a mustard-seed tempering

Rasam is the thin, sour, peppery broth that runs through every Tamil Nadu meal, poured over rice after sambar or sipped from a tumbler when you have a cold. This tomato version is the everyday kind: ripe tomatoes and tamarind simmered with crushed garlic, black pepper and cumin, then lifted with a tempering of mustard seeds, dried chilli and curry leaves. It's light, warming and ready in 25 minutes. Serve it with plain rice and a dry vegetable, or on its own in a cup. Chef's tip: once you add the spice mix, take the rasam off the heat as soon as it froths up; boiling it hard turns the flavour flat and the pepper harsh.

Method

0/6 done
  1. Step 1: Put 3 ripe tomatoes in a pan with 1 tbsp tamarind paste, 2 ½ cups water, ¼ tsp ground turmeric, 1 tsp salt, ½ tsp jaggery or brown sugar and half the chopped coriander stems from 3 tbsp fresh coriander. Squeeze the tomatoes with your hand as they go in to release their juice.

    2 min
  2. Step 2: Bring to the boil, then simmer on a medium heat for 8–10 minutes until the tomatoes are soft and the raw tamarind smell has gone.

    10 min
  3. Step 3: Meanwhile, pound 1 tsp black peppercorns and 1 tsp cumin seeds to a coarse powder in a mortar, then add 4 cloves garlic and crush it into the spices, skins and all; the skins add flavour and are strained out or left in, as you prefer.

  4. Step 4: Add the pepper-garlic mix to the pan and lower the heat. Watch it closely: in 1–2 minutes a layer of froth will rise to the top. Take it off the heat at once.

    2 min
  5. Step 5: For the tempering, heat 1 tbsp vegetable or sesame oil in a small pan over a medium heat, add ½ tsp black mustard seeds and let it pop, then add 1 dried red chilli, 10 fresh curry leaves and ¼ tsp gluten-free asafoetida (hing). Pour it sizzling into the rasam.

    1 min
  6. Step 6: Scatter with the coriander leaves, cover for 2 minutes to let the flavours settle, and serve hot, poured over rice or in cups.

Masala khakhra

Khakhra are thin chapaties roasted slowly on a griddle until they turn crisp, like a cracker. This masala version adds gram flour, fresh fenugreek, turmeric and chilli to the wheat dough. They are a light Gujarati breakfast or tea-time snack, and lovely with pickle, chutney or a smear of butter. You can also make them in a roti maker.

Sabudana khichdi

Sabudana khichdi is the dish that sees Maharashtra through every vrat (fast), from Navratri to Ekadashi, but it's so good that people eat it any day of the week. Soaked sago pearls are tossed in a pan with crushed roasted peanuts, cubes of potato, cumin and green chilli until each pearl turns glassy and separate, then finished with lemon and coriander. It's soft, chewy, nutty and gently hot. Fasting rules vary from family to family, so check yours; this version uses rock salt and no asafoetida, onion or garlic. Traditionally it's cooked in ghee; use ghee instead of oil if you aren't keeping it vegan. Chef's tip: soak the sago in just enough water to cover by the height of the pearls themselves, no more; too much water is the reason khichdi turns into one sticky lump.

Bagara baingan

Bagara baingan is a Hyderabadi wedding dish of small aubergines cooked whole in a dark, tangy gravy of roasted peanuts, sesame, dried coconut and tamarind. Unlike a Gujarati stuffed brinjal, the aubergines here are only quartered at the base and fried until silky, then left to soak up a thin-but-rich sauce that is finished with a tempering, the 'baghar' that gives the dish its name. It's sour, nutty and gently spiced, and is served with biryani, bagara rice or plain rice. Chef's tip: choose small, glossy purple aubergines that feel heavy for their size; soft, light ones are full of seeds and turn mushy before the gravy has a chance to cling.
