Field notes · North Indian gravy
Three chickens. One base. One defector.
Butter chicken and chicken curry are not different recipes. They are the same onion–tomato masala, stopped at different moments and finished in different directions. Chilli chicken never touches it at all.

One · The base
Cook the masala. Watch it change.
Recipes give you minutes. Cooks give you colour. Drag the dial and the masala moves from raw to done — the same base that becomes both gravies below.

Oil separates
The masala pulls into a single mass and a rim of orange oil pools at the edge of the pan. This is the only doneness cue that matters. Everything after this point is a choice.
- 0:00Oil, hot. Whole spices until they sputter.
- 0:40Onion, sliced fine. Salt now — it pulls the water out.
- 4:00Ginger–garlic paste. Cook until it stops smelling raw.
- 6:00Tomato. It loosens everything, then tightens again.
- 9:00Ground spices, with a splash of water so they bloom.
- 18:00Oil at the edges. Stop. The base is done.
Two · The split
Same pan, three endings
Two of these dishes argue about how far to take the base. The third refuses the argument entirely.
Takes the base all the way
Chicken curry
The honest one. You cook the base past brick red, then put raw chicken straight into it and let the meat give up its own liquid. Nothing softens the edges — no cream, no cashew, no butter. What you taste is browned onion and time.
It gets better overnight, which is the whole argument for making it on a Sunday. Every family's version is slightly wrong to every other family.
On top of the base Curd, garam masala, green chilli

Leaves the base early, on purpose
Butter chicken
A restaurant dish pretending to be a home one. It ducks out of the base before the onions brown — you want tomato sweetness, not caramel depth — then simmers, gets blitzed smooth, and comes back enriched with butter, cashew and cream.
The chicken is cooked separately and joins at the end, carrying char from the tandoor. Kasuri methi is crushed between your palms over the pan in the last thirty seconds. Skip it and the dish tastes like tomato soup.

- Finish

Never enters the base at all
Chilli chicken
Indo-Chinese, born in Kolkata's Hakka kitchens, and it plays by wok rules instead of gravy rules. Chicken goes into cornflour batter and hot oil. The pan gets screaming hot, aromatics go in for seconds rather than minutes, and the whole thing finishes in about four.
The green chillies are the point. Slit lengthwise and dropped into hot oil, they give an aroma that reaches the back of your nose before any heat reaches your tongue. Cook them a moment too long and you lose it.
Instead of the base Green chilli, white pepper, garlic — and nothing above
Why it isn't a curry
- Base
- None. There is no masala.
- Chicken
- Battered and deep-fried first
- Heat
- Highest your burner goes, start to end
- Season
- Soy, vinegar, green chilli, white pepper
- Clock
- Four minutes in the wok, not eighteen
Two and a half · The fork
This is where they part
Everything above this line is one pan. Everything below it is a choice about what to do next — and one of the three never turns up to make it.
The basestage five
Chicken currytakes it all the way
Butter chickenleaves early, comes back rich
Chilli chickendoes not arrive here
A diagram of the split. One pan of onion-tomato base at the top divides along two curves into chicken curry on the left, cooked darker, and butter chicken on the right, stopped earlier and enriched with cream. A fourth vessel, a wok holding chilli chicken, sits apart on the right; the line reaching toward it breaks off before it connects, because chilli chicken never uses the base at all.
Three · The clock
Where the three dishes spend their time
Read across. The gravies front-load everything into one long browning; the wok spends its time on prep and almost none on heat.
Chicken curry42 min · one pan
Butter chicken24 min · two pans
Chilli chicken16 min · wok
Chicken curry runs forty-two minutes in a single pan: eighteen minutes building the base, a short sear, eighteen minutes of simmering, then a finish. Butter chicken runs twenty-four minutes across two pans, with the chicken charring in parallel while the gravy is blended and enriched. Chilli chicken runs sixteen minutes total, of which only the final four are spent in the wok.
Butter chicken is the only one of the three that needs two burners. That single constraint is why it belongs to restaurants, and why the home version never tastes quite the same.
Four · Green chilli
Heat is the boring axis
Scoville measures one thing badly. Plot aroma against it and the Indian green chilli sits somewhere nothing else does — moderate heat, enormous smell.
The horizontal axis is logarithmic. On a linear one, everything except the ghost pepper would pile into the left edge.

The Indian green chilli, and the reason chilli chicken smells the way it does. Slit it, drop it in hot oil, and the volatile compounds hit the air within seconds — grassy, sharp, almost citrus. That smell is gone if you cook it for more than a minute, which is exactly why the wok phase is short.
- Kashmiri — around 1,800 SHU. Colour, not heat.
- Byadgi — around 10,000 SHU. Mild, wrinkled, deep red.
- Hari mirch — around 30,000 SHU with the highest aroma of the group.
- Guntur sannam — around 40,000 SHU. Blunt heat, little smell.
- Bird's eye — around 100,000 SHU. Sharp and quick.
- Bhut jolokia — around 1,000,000 SHU. Almost no aroma to speak of.
Five · The dabba
Seven tins, seven jobs
Every Indian kitchen has one steel box with seven compartments and no labels. Pick a tin to see what it does — and what breaks when it's missing.
Ground blend · added off the heat
Garam masala
- Goes in
- Last. After the heat is off.
- Job
- Aroma, not flavour. Warmth you smell rather than taste — cardamom, clove, cinnamon, black pepper.
- Skip it
- The curry tastes finished but flat. Nothing announces itself when the lid comes off.
- Garam masala — last, off the heat. Aroma rather than flavour.
- Haldi — early, with the ginger–garlic. Earthy base note and colour.
- Kashmiri lal mirch — with the tomato. Deep red colour, mild heat.
- Dhania — the bulk of the spice. Body and a faint citrus.
- Jeera — first, into hot oil. Must sputter before anything else goes in.
- Kasuri methi — crushed by hand at the very end. Essential to butter chicken.
- Kali mirch — sharp, immediate heat. The Indo-Chinese kitchen's chilli.

So which one are you actually making?
Three questions. It's a constraint problem, not a taste problem.
Answer all three and the pan picks itself.

Learn the base and you stop needing recipes
Once you can see the moment the oil separates, every gravy in this cuisine becomes a single decision about what to do next: darken it, enrich it, or walk away from it entirely.
