Three red chillies dominate Indian kitchens, and they are not interchangeable. Put Guntur where Kashmiri belongs and your rogan josh is inedible. Put Kashmiri where Guntur belongs and your Andhra pickle tastes of nothing. This is a short, practical guide to telling them apart and using each one properly.
The three at a glance
| Chilli | Heat | Colour | Grown in | Use it for |
|---|---|---|---|---|
| Kashmiri | Very mild roughly 1,000–2,000 SHU |
Deep red, very high | Kashmir; much sold as Kashmiri is Byadgi-type from Karnataka | Colour without heat — tandoori, rogan josh, butter chicken, tikka marinades |
| Byadgi | Mild roughly 8,000–15,000 SHU |
Very deep red, wrinkled skin | Byadgi, Karnataka | Bisi bele bath, sambar, Mangalorean and Udupi cooking, chutney powders |
| Guntur | Hot roughly 25,000–40,000 SHU |
Bright red, moderate | Guntur, Andhra Pradesh | Andhra and Telangana cooking, pickles, karam podi, anywhere heat is the point |
SHU = Scoville Heat Units. Ranges are indicative: heat varies considerably by crop year, soil and how much of the seed and placenta is milled in.
Kashmiri: colour, not heat
Kashmiri chilli exists to make food red. Its heat is so low that you can use a tablespoon of the powder in a marinade without the dish reading as spicy at all, and that is exactly why it sits in every tandoori recipe. The pod is short, broad and smooth-skinned, and the powder is a deep brick red rather than an orange red.
One honest note, because it affects what you buy: a great deal of what is sold as "Kashmiri chilli" in India is not grown in Kashmir. Genuine Kashmiri production is small. Much of the market is Byadgi-type chilli from Karnataka, or Kashmiri-type cultivars grown elsewhere, sold under the name for its colour profile. That is not adulteration — it is a naming convention — but it is why the price range is so wide and why the colour varies between brands.
The thing actually worth paying for is colour value, measured in ASTA units. A good Kashmiri-type powder sits high on that scale naturally. A cheap one gets there with dye. If a powder is startlingly red and costs less than the whole pods would, be suspicious — and run the water-glass test from our guide on spotting adulterated spice at home.
Byadgi: the one most South Indian cooking actually wants
Byadgi is the quieter answer to the same problem. It gives a deeper, slightly darker red than Kashmiri with a little more warmth behind it, and it carries a distinct fruity, almost smoky note that Kashmiri does not have. The pods are long, slender and heavily wrinkled — that wrinkling is the easiest way to identify them by eye.
If you cook Karnataka or coastal Konkan food, Byadgi is the correct chilli for bisi bele bath powder, for saaru, for Mangalorean fish curries and for most chutney powders. It is also the chilli the oleoresin industry buys most heavily, precisely because of that colour, which is part of why good Byadgi is not cheap.
Guntur: heat as the main event
Guntur — usually the Sannam S4 variety — is where Andhra and Telangana cooking gets its character. It is several times hotter than Kashmiri and it is meant to be. The heat is clean and forward rather than lingering, which is why it works in karam podi, in avakaya and other pickles, and in Andhra-style gravies where the chilli is the dominant flavour and not a background colour.
Guntur is also the district that makes India the world's largest chilli producer and exporter — the Guntur market yard is the biggest chilli market in Asia. If you have eaten chilli anywhere in the world, some of it came from within fifty kilometres of there.
Use it with a lighter hand than you would Kashmiri. A teaspoon of Guntur powder is not a teaspoon of Kashmiri powder.
Telling them apart by eye
If you buy whole pods — and you should — the three are genuinely easy to distinguish once you have seen them side by side.
- Kashmiri pods are the shortest and broadest of the three, with relatively smooth, taut skin and a rounded shoulder. The red is dense and even.
- Byadgi pods are long, narrow and unmistakably wrinkled — the skin puckers along the length of the pod as it dries. The colour is the darkest of the three, closer to maroon than scarlet.
- Guntur pods are medium length, straighter, with thinner and smoother skin and a brighter, more orange-leaning red. They also tend to rattle more when shaken, because there is proportionally more seed.
In powder form this gets much harder, which is the honest argument for buying whole. A dyed powder can be made to look like any of them. A wrinkled Byadgi pod cannot.
Storing it so it lasts
Chilli keeps far better than most people assume, provided you protect it from the three things that destroy it: light, heat and air.
Keep powder in an opaque, airtight container — steel or ceramic rather than the clear glass jar on the shelf above the hob, which is the single worst spot in most kitchens. Whole pods keep longest of all: in a sealed tin away from light they hold colour and aroma for a year or more, against roughly three to four months for powder before it noticeably flattens.
Do not refrigerate powder. Taking a cold jar in and out of a warm kitchen condenses moisture inside it, and damp chilli powder cakes and grows mould. A cool, dark cupboard is better than a fridge.
How to blend them
Most experienced South Indian cooks do not choose one — they blend, and they blend for two different variables at once.
- Colour-led dishes (tandoori, tikka, rogan josh, butter chicken): Kashmiri alone, or Kashmiri with a small pinch of Guntur if you want a little bite behind the colour.
- Sambar, rasam and chutney powders: mostly Byadgi for depth, with roughly one part Guntur to four parts Byadgi for heat.
- Andhra pickles and karam: Guntur-led, with some Byadgi to keep the colour from going dull orange.
- Everyday North Indian gravies: two parts Kashmiri to one part Guntur is a reliable house blend.
Blending your own is much easier if you buy whole pods and mill them, because you control the ratio and you control how much seed goes in. Seed and the white placenta carry most of the capsaicin — mill more of it in and the same chilli comes out hotter.
Whole pods or ready powder?
Two reasons to prefer whole, or freshly milled.
Aroma goes first. The volatile compounds that make a chilli smell like anything begin leaving the moment it is ground and the cut surface meets air. Capsaicin — the heat — is stable and stays. So an old powder is not milder; it is hotter relative to its flavour, flat and harsh rather than fragrant. That is why a six-month-old supermarket packet tastes one-dimensional.
Colour fades too. The carotenoid pigments that give Kashmiri and Byadgi their red oxidise under light and heat. A powder stored in a clear jar on a sunny shelf loses visible colour within months — which, incidentally, is one commercial motive for adding dye in the first place.
Both problems disappear if the chilli is whole until shortly before you use it.
What we stock
- Premium Kashmiri Chilli Powder — milled from whole pods for colour, no added dye, no anti-caking agent.
- Guntur Chilli Powder — Sannam-type, milled to order, for Andhra heat.
Both are milled at the counter rather than pre-packed, and both carry published colour-value and added-dye screening on our lab reports page.
If you are in Hyderabad, bring your own ratio to the Kondapur or Serilingampally counter and we will mill the blend you actually cook with, rather than the one that happened to be bagged.
