British Curry: The History of Chicken Tikka Masala and Britain's Adopted National Dish

The story of curry in Britain begins not in the 1960s but considerably earlier. The first documented Indian restaurant in Britain, the Hindoostane Coffee House, opened in London's Portman Square in 1810, serving 'Indian dishes in the highest perfection.' Its owner, Sake Dean Mahomed, had served in the Bengal Army and understood both the flavours of his homeland and the curiosity of his adoptive country. The restaurant failed within two years — Britain wasn't ready — but the seed was planted.

The real transformation came after 1947, when Partition created enormous displacement across the Indian subcontinent, and particularly after the 1971 Bangladesh Liberation War, which drove a significant wave of Sylheti immigrants to Britain. Many settled in cities, opened restaurants and worked in the catering trade, where long hours and low barriers to entry made it accessible. By the late 1970s, 'going for a curry' had become a Friday-night ritual for working-class communities across the Midlands, the North and Scotland.

Chicken tikka masala itself — chunks of tandoor-roasted chicken folded into a spiced tomato-cream sauce — is widely believed to be a British invention. The most repeated origin story places it in Glasgow's Shish Mahal restaurant in the 1970s, where chef Ali Ahmed Aslam allegedly added tomato soup and spices to satisfy a customer who found the dish too dry. Whether entirely true or not, it illustrates how British curry evolved: adapting traditional cooking to local palates, British ingredients and the specific atmosphere of the high-street curry house.

Authentic curry house cooking relies on a specific pantry that differs subtly from domestic Indian cooking. The backbone is a pre-cooked base gravy — a slow-cooked blend of onions, tomatoes, ginger, garlic and whole spices that forms the starting point for dozens of different dishes. This is the curry house secret that most home recipes overlook.

For chicken tikka masala specifically, you need: boneless chicken thighs (thighs stay juicier than breast under high heat), full-fat yoghurt for the marinade, Kashmiri chilli powder for its brilliant red colour and mild heat, smoked paprika, ground cumin, ground coriander, garam masala, turmeric, fresh ginger root, garlic, a tin of good-quality chopped tomatoes (Mutti or Cirio work well), double cream and a block of ghee or good vegetable oil. Methi — dried fenugreek leaves — is the finishing touch that gives curry house dishes their characteristic slightly bitter, nutty depth. Many British corner shops and all large supermarkets stock it, often under the Natco or East End brands.

For the tandoori-style charring without a clay oven, you need a cast-iron skillet or griddle pan capable of withstanding very high heat. Some cooks use a blowtorch for additional char. The Maillard browning achieved in this step — not the sauce — defines the dish.

Curry house technique has three pillars: the base gravy, the high-heat char and the rapid finishing. The base gravy is made in large batches — in restaurants, often 20 litres at a time — by sweating onions very slowly in oil until they are completely soft and beginning to colour, then adding blended tomatoes, ginger-garlic paste, ground coriander and turmeric before simmering for an hour and blending smooth. At home, a smaller version (2–3 litres) can be made and frozen in portions, enabling you to cook restaurant-quality curry in under 15 minutes on a weeknight.

The high-heat char is achieved by cooking marinated chicken pieces in a very hot pan or under the grill on maximum heat until the exterior is blistered and slightly carbonised. Do not crowd the pan — cook in batches if necessary. The slight bitterness of the char balances the sweet, creamy sauce.

Finishing technique separates the good from the great: add the base gravy to a very hot pan, introduce the spices bloomed in ghee, add the chicken, then the cream in the final 90 seconds only. Cream added too early breaks and turns greasy. Experienced curry house chefs finish with a small knob of cold butter ('tadka') stirred in off the heat to give the sauce its characteristic glossy restaurant sheen.

Ingredients (serves 4): 800 g boneless, skinless chicken thighs; 150 g full-fat yoghurt; 1 tbsp Kashmiri chilli powder; 1 tsp ground cumin; 1 tsp garam masala; 1 tsp turmeric; 1 tbsp ginger-garlic paste; salt; 2 tbsp ghee or vegetable oil; 1 large onion, finely diced; 2 tbsp tomato purée; 400 g chopped tomatoes; 150 ml double cream; 1 tsp dried methi leaves; fresh coriander to serve.

Step 1 — Marinate: Mix yoghurt, Kashmiri chilli, cumin, garam masala, turmeric, ginger-garlic paste and a generous pinch of salt. Coat the chicken thighs thoroughly, cover and refrigerate for at least 4 hours, preferably overnight.

Step 2 — Char the chicken: Heat a griddle or heavy frying pan until smoking. Cook chicken pieces in batches, pressing lightly, until deeply charred on both sides (approximately 4–5 minutes each side). Set aside and rest for 5 minutes, then cut into 4 cm chunks.

Step 3 — Build the sauce base: In a wide, heavy pan, heat ghee over medium-high heat. Add onion and cook, stirring regularly, for 15–18 minutes until deep golden. Add tomato purée, stir for 2 minutes.

Step 4 — Add tomatoes and spices: Add chopped tomatoes, a pinch each of cumin, garam masala and Kashmiri chilli. Season well. Simmer vigorously for 15 minutes, stirring often, until the sauce has reduced and the oil begins to separate at the edges — this indicates the masala is cooked through.

Step 5 — Combine chicken and cream: Add charred chicken to the sauce and stir to coat. Reduce heat to low. Stir in double cream and the soaked methi leaves. Simmer gently for 5 minutes. Taste and adjust salt.

Step 6 — Finish and serve: Remove from heat and stir in a small knob of cold butter for gloss. Serve with basmati rice and warm naan bread (Peshwari naan is the classic pairing). Garnish with fresh coriander.

Ingredients (serves 4): 900 g bone-in lamb shoulder, cut into large cubes; 3 tbsp ghee; 2 large onions, thinly sliced; 6 garlic cloves, minced; 3 cm fresh ginger, grated; 2 tsp Kashmiri chilli powder; 2 tsp ground coriander; 1 tsp ground cumin; 1 tsp garam masala; 1/2 tsp ground cardamom; 3 whole cloves; 2 bay leaves; 400 g chopped tomatoes; 200 ml lamb stock or water; salt; fresh mint and yoghurt to serve.

Step 1 — Brown the lamb: Pat lamb pieces dry with kitchen paper and season generously with salt. Heat ghee in a large, heavy casserole over high heat. Brown lamb in batches without crowding, turning until all sides are deeply coloured (about 6–8 minutes per batch). Remove and set aside.

Step 2 — Cook the base: In the same pan, add cloves and bay leaves to the remaining fat. Fry for 30 seconds. Add sliced onions and cook over medium heat for 20 minutes, stirring regularly, until they are deeply caramelised and reduced to about a third of their original volume.

Step 3 — Add aromatics: Add garlic and ginger, stir for 2 minutes. Add Kashmiri chilli, ground coriander, cumin and cardamom. Stir constantly for 90 seconds, adding a splash of water if the spices catch.

Step 4 — Tomatoes and stock: Add chopped tomatoes and cook, stirring vigorously, for 8–10 minutes until the oil visibly separates around the edges. Add stock or water and stir well to deglaze any fond from the bottom.

Step 5 — Slow braise: Return the lamb to the pan. Bring to a gentle simmer, cover tightly and cook on the lowest possible heat for 1 hour 30 minutes, checking every 30 minutes and adding a splash of water if the sauce is becoming too thick. The lamb should be completely tender and yielding.

Step 6 — Finish: Stir in garam masala and cardamom. Taste and adjust salt. Serve with pilau rice, a dollop of cold yoghurt, fresh mint leaves and warm chapati.

British curry is not homogeneous — distinct regional styles have developed in different cities, reflecting the communities that shaped them. Birmingham's Balti, served in a thin pressed-steel wok and cooked and eaten from the same vessel, originated in the Sparkbrook and Moseley districts in the 1970s. The Balti triangle — a stretch of Ladypool Road and Stoney Lane — still draws Midlanders from across the region for enormous, fragrant dishes eaten with huge tear-off naan bread rather than cutlery.

Glasgow has its own curry culture centred on the West End and the South Side, where Pakistani and Indian restaurants serve a richer, slightly sweeter style that reflects local palates. The Glasgow curry differs subtly from London equivalents: sauces are often thicker and the heat level is calibrated for a Scottish winter.

Bradford — sometimes called the curry capital of England — has a particularly strong Kashmiri and Pakistani culinary tradition, with restaurants on Westgate and Lumb Lane noted for their kadahi and karahi preparations: simple, robust dishes cooked in traditional round-bottomed pans with minimal dairy and maximum spice.

In London, Brick Lane in Tower Hamlets remains the symbolic heart of Bangladeshi-British cooking, though culinary critics increasingly point to Tooting, Green Street and Southall as offering more authentic regional Indian cooking. Northern Ireland has a thriving curry scene centred on Belfast's Golden Mile, where Pakistani and Indian restaurants serve dishes with a distinctive Ulster flair.

For the definitive restaurant chicken tikka masala, food critics consistently recommend Dishoom (multiple London locations plus Edinburgh, Manchester and Birmingham) for its Irani café-inspired Bombay cooking; Bundobust in Leeds and Manchester for innovative street-food curries; and Mowgli Street Food, founded by barrister-turned-restaurateur Nisha Katona, for home-style Indian cooking across the North of England. Glasgow's Mother India has been a local institution since 1990 and its masala dishes are considered benchmark examples of the Scottish-Indian style.

For the traditional high-street curry house experience — flock wallpaper, popadoms, lime pickle and all — cities including Bradford, Leicester and Birmingham offer dozens of independently owned restaurants where recipes have been refined over decades and the value for money remains extraordinary.

At home, the single most effective upgrade is making a batch base gravy and freezing it in 300 ml portions. This takes two hours on a Sunday afternoon and transforms weeknight cooking completely. Invest in fresh whole spices and grind them yourself: a £10 electric coffee grinder dedicated to spices makes the difference between flat, dusty sauces and the vibrant, complex layers that define genuine curry house cooking. Toasting whole cumin and coriander seeds in a dry pan before grinding unlocks considerably more flavour than pre-ground alternatives.
