Indian Regional Cuisine: From Butter Chicken of the North to Dosa of the South

Indian culinary history stretches back at least 5,000 years to the Indus Valley Civilisation, where archaeological evidence suggests the use of turmeric, ginger, and mustard seed. Ayurveda — the ancient system of medicine and life philosophy dating to approximately 1500 BCE — codified a relationship between food and health that still governs cooking across the subcontinent: the six tastes (sweet, sour, salty, pungent, bitter, astringent), the three doshas (bodily constitutions), and the heating and cooling properties of individual ingredients all inform how spices are combined and dishes are constructed.

The Mughal Empire (1526–1857), which ruled from Delhi, brought Persian and Central Asian culinary refinements to the north: rice pilafs (pilau), the tandoor oven, yoghurt-based marinades, and the rich, ghee-laden, nut-thickened kormas and biryanis of the Mughal court. This imperial cuisine became the foundation of what the world now recognises as North Indian restaurant food.

The south, largely untouched by Mughal rule, developed independently along Dravidian, Buddhist, and Brahminic lines. Fermented rice and lentil batters producing idli and dosa, coconut-based curries, tamarind-soured sambars, and the rice-centred meal structure (sadhya) of Kerala are all expressions of southern culinary philosophy — lighter in fat content than the north, more sour, more heavily spiced in absolute terms, and with a much higher proportion of vegetable and lentil-based dishes.

The arrival of Portuguese traders in Goa in the early 16th century introduced chillies, vinegar, and pork to the western coast — producing the unique Goan vindaloo (a corruption of vinho d'alhos, wine and garlic) and the Catholic-influenced pork sorpotel. Later, British colonialism, the spice trade, and the movement of communities through the empire created the extraordinary regional diversity that characterises modern Indian cooking.

Whole spices form the foundation of most Indian cooking and should ideally be bought whole and ground as needed. The essential set: cumin seeds (jeera), coriander seeds (dhania), brown and black mustard seeds (rai/sarson), fenugreek seeds (methi), fennel seeds (saunf), black pepper, cardamom pods (green and black), cloves (laung), cinnamon bark (dalchini), turmeric (haldi, used as powder), dried red chillies, and bay leaves.

Ghee (clarified butter) is the primary cooking fat of North India and many Hindu cooking traditions. Its high smoke point and rich, nutty flavour make it superior to butter for high-heat applications. Good ghee is easily made at home from unsalted butter.

Tamarind (imli) is the primary souring agent of South Indian cooking — tart, fruity, and complex. Available as compressed blocks (the most concentrated form), paste, or concentrate. Essential for sambar, rasam, and chutneys.

Coconut — grated fresh or desiccated for South Indian dishes, as coconut milk for Kerala curries, as coconut oil for coastal and Kerala cooking.

Urda dal (split black lentils with skin, also called black urad) is soaked and ground for idli and dosa batter. Masoor dal (red split lentils) is the fastest-cooking everyday lentil. Toor dal (yellow split peas) is the base of sambar. Chana dal (split chickpeas) provides nutty richness in South Indian cooking.

Asafoetida (hing) is a dried resinous gum with an intensely sulphurous raw smell that transforms in hot oil into a flavour resembling garlic and onion — it is used in Brahminic and Jain cooking as a substitute for alliums, and in tiny quantities to season lentil dishes and prevent flatulence.

Kashmiri chilli powder is mild in heat but brilliant red in colour — used to produce the vivid colour of tandoori marinade and many North Indian curries without excessive fire.

Tadka (tempering spices in hot fat) is the technique that most distinguishes Indian cooking from every other culinary tradition. Whole spices — cumin seeds, mustard seeds, dried chillies, curry leaves, asafoetida — are added to very hot ghee or oil and fried for 30 to 90 seconds until they crackle, pop, and release their aromatic compounds. This bloom of flavour is then either used as the base for further cooking or drizzled hot as a finishing element over a completed dish. The order in which spices go into the tadka matters: mustard seeds pop first, then harder seeds, then curry leaves (which must be added carefully as they spit aggressively).

Building a masala base requires patience and good heat management. Onion is cooked until it progresses through five stages: translucent, golden, brown, deeply brown, and finally jammy — this last stage takes 20 to 30 minutes and produces the mahogany-coloured paste that underpins North Indian restaurant sauces. Garlic and ginger paste go in after the onion reaches colour, then ground spices, then tomato, and each element must cook out before the next is added.

Fermented batter preparation for idli and dosa requires blending soaked urad dal and parboiled rice separately (a wet grinder produces finer, airier results than a blender) then combining and fermenting at warm room temperature for 8–12 hours until bubbled and slightly sour. The fermentation is what produces the characteristic tanginess and the light, aerated texture of good idli.

Dum cooking (cooking under pressure in a sealed pot) produces biryani and certain slow-cooked stews. Rice and marinated meat are layered in a heavy pot, the lid is sealed with a paste of flour and water, and the pot cooks over very low heat — the steam builds inside, cooking the rice gently in the aromatic meat juices. The seal is broken at the table with a knife, releasing trapped fragrance.

Griddle cooking for roti and paratha requires a dry tawa (flat iron griddle) at medium-high heat. The dough is pressed thin and cooked in 90-second intervals, flipped multiple times, and finished directly over an open flame for charring and puffing (in the case of chapati/phulka).

Dal makhani is one of the great achievements of North Indian cooking — whole black urad lentils simmered overnight with kidney beans in a rich, creamy tomato and butter sauce. Originating in the tandoor-equipped Punjabi dhabas (roadside restaurants) of the mid-20th century, it was refined into an icon by the restaurant Moti Mahal in Delhi under the pioneering chef Kundan Lal Gujral.

Ingredients (serves 6): 250 g whole black urad dal (sabut urad), soaked overnight; 50 g red kidney beans (rajma), soaked overnight; 1 litre water; 1 tsp salt; 3 tbsp ghee or butter; 1 large onion, very finely diced; 5 garlic cloves, minced; 1 tbsp fresh ginger, grated; 2 tsp Kashmiri chilli powder; 1 tsp garam masala; 1 tsp ground cumin; 400 g canned crushed tomatoes; 100 ml double cream; 30 g butter; additional cream and a knob of butter to finish.

Method: Pressure-cook the soaked, drained lentils and beans in 1 litre water with 1 tsp salt for 25–30 minutes (or simmer covered for 90 minutes–2 hours) until very tender and beginning to break down — the dal should be soft but not completely mashed. In a separate heavy pan, heat ghee over medium heat. Cook the onion for 25 minutes, stirring often, until deeply golden-brown. Add garlic and ginger and cook 3 minutes. Add Kashmiri chilli powder, cumin, and half the garam masala; cook 1 minute. Add tomatoes and cook, stirring, for 20 minutes until the fat separates from the masala. Combine masala with the cooked dal and simmer together for 30 minutes on very low heat, stirring every few minutes (dal burns easily). Add double cream and 30 g butter and simmer 15 minutes more. Finish by stirring in remaining garam masala and a final knob of butter. Serve with roomali roti or naan, topped with a swirl of cream.

The masala dosa is South India's most internationally celebrated dish — a thin, crisp, sour fermented rice crepe filled with spiced potato, served with coconut chutney and sambar. It requires advance preparation (the batter ferments for up to 12 hours) but the technique, once learned, produces results of extraordinary quality.

For the batter (makes 12–15 dosas): 200 g parboiled rice; 50 g raw rice; 100 g whole urad dal with skin; ½ tsp fenugreek seeds; 1½ tsp salt; water as needed.

For the potato filling: 500 g floury potatoes, boiled, peeled, and roughly mashed; 2 tbsp coconut oil; 1 tsp black mustard seeds; 8–10 fresh curry leaves; 2 small dried red chillies; 1 medium onion, finely sliced; 1 tsp fresh ginger, grated; 1 green chilli, slit; ½ tsp turmeric; salt to taste; 2 tbsp fresh coriander.

Batter method: Soak rice separately from dal plus fenugreek for 4 hours in cold water. Drain both. Grind dal with fenugreek to a very smooth, airy paste using a blender, adding water gradually. Grind rice to a slightly coarser paste. Combine, add salt, mix well, and ferment at warm room temperature (25–28°C) for 8–12 hours until bubbled and sour-smelling.

Filling method: Heat coconut oil over medium-high heat. Add mustard seeds and wait until they pop. Add curry leaves and dried chillies — step back as they spit. Add onion and cook 8 minutes until golden. Add ginger and green chilli, cook 1 minute. Add turmeric. Fold in mashed potato and salt. Stir in coriander. Cool slightly.

Dosa method: Heat a non-stick or cast-iron griddle over medium-high heat. Brush very lightly with oil. Pour a ladle (80–100 ml) of batter in the centre and immediately spread in concentric circles from centre outward with the back of the ladle — working quickly to achieve a thin, even crepe. Drizzle 1 tsp oil around the edges. Cook for 2–3 minutes until the edges lift and the base is golden-brown and crisp. Place 2–3 tablespoons of filling in a line across the centre. Fold the dosa over the filling and serve immediately with coconut chutney and sambar.

Kerala (southwestern coast) has a cooking tradition built on coconut in every form — coconut oil, coconut milk, grated coconut — combined with black pepper (a Keralan original), curry leaves, and fresh seafood. The sadya, a traditional vegetarian feast served on banana leaves for festivals, includes 20 to 28 individual preparations and represents one of the most elaborate vegetarian meals in the world.

Kashmir (far north) has a Mughal-influenced cuisine of extraordinary sophistication: rogan josh (lamb in aromatic gravy coloured with Kashmiri chilli), yakhni (yoghurt-braised lamb), gushtaba (pounded meat dumplings in cream sauce), and haak (local Kashmiri spinach) cooked in a distinctive wazwan feast tradition where a single professional cook (waza) prepares upward of 36 courses for a wedding.

Rajasthan (northwest desert) developed a cuisine that accounts for scarcity of water and fresh produce: dal baati churma (twice-baked wheat dumplings with lentils and sweetened flour), ker sangri (dried berries and beans), and the use of yoghurt as a souring and binding agent in many dishes in place of tomato.

Goa (western coast, Portuguese-influenced) produces vindaloo, xacuti (a coconut curry with roasted spices), and cafreal (a herb-marinated grilled chicken with Portuguese roots), all reflecting the meeting of Hindu, Muslim, and Catholic food traditions in a compact coastal region.

Bengal (east) has a sophisticated fish-and-mustard cooking tradition — shorshe ilish (hilsa fish in mustard sauce) is an almost sacred dish — and the most developed sweet-making tradition in India, including rasgulla, mishti doi, and sandesh.

The structure of an Indian meal varies by region but shares a common principle: balance of flavours, textures, and nutritional completeness through combination rather than sequence. A North Indian thali presents multiple small portions simultaneously — dal, sabzi (vegetable), protein, rice, roti, raita, pickle, and papad — each component distinct but designed to be eaten together.

For a North Indian dinner for four: serve dal makhani alongside a dry potato-and-pea sabzi, basmati rice, freshly made roti or purchased naan, cucumber raita (yoghurt with cucumber, cumin, and mint), and a small bowl of mango achaar (pickle). The raita cools spiced dishes; the pickle punctuates each mouthful with a jolt of sourness or heat.

For a South Indian breakfast spread: serve masala dosa with coconut chutney and sambar, plus a plate of idli (steamed rice cakes) for those who want a softer option, and a small pot of filter coffee (South Indian filtered coffee with chicory, served with warmed milk and sugar in small stainless-steel tumblers).

For a Keralan dinner: Kerala fish curry in coconut milk with appam (lacy fermented rice flour pancakes), alongside a simple thoran (dry-cooked vegetable with grated coconut and curry leaves). Finish with payasam (coconut milk pudding with vermicelli).

Etiquette: eating with the right hand is traditional across most of India — tear bread, mix rice and curry with fingers, and gather into a small mound before eating. Never use the left hand for food. Offering food to guests before serving yourself is standard hospitality.
