Mangrail in English: What Kalonji (Nigella Seeds) Is & How to Use
Kalonji — known as nigella seeds, mangrail, or kalaunji across different parts of India — is one of the most underrated spices in the Indian kitchen. Those tiny, black, slightly angular seeds have a pungent, slightly bitter, onion-like flavour that is unlike anything else in your spice box. Once you know how to use them, you will find yourself reaching for them far more often.
What Does Kalonji Taste Like?
Kalonji has a bold, slightly bitter, and earthy flavour with a faint hint of oregano and onion. When added to hot oil for a tadka, the bitterness mellows and the seeds release a warm, peppery aroma. They are not overwhelming when used in moderation — a pinch goes a long way.
5 Classic Ways to Use Kalonji in Indian Cooking
1. Tadka for dal and sabzi: Add half a teaspoon of ODM Kalonji to hot mustard oil or ghee at the start of your tadka. The seeds will crackle and flavour the entire dish. This works especially well in Bengali-style dals, aloo sabzi, and stuffed brinjal.
2. Naan and paratha: Sprinkle kalonji seeds on the surface of naan dough before baking or on paratha before the second roll. They add a savoury, nutty bite that makes plain bread feel restaurant-quality. This is the classic reason naan from a tandoor always tastes different from homemade — kalonji is the secret.
3. Pickle (achaar): Kalonji is a key ingredient in most North Indian mango and lime pickles. Its slight bitterness balances the heat and sourness of the pickle beautifully. If you are making achaar at home, add 1 teaspoon of kalonji per 500 g of fruit.
4. Panchphoron blend: Kalonji is one of the five seeds in panchphoron, the quintessential Bengali whole-spice blend alongside cumin, mustard, fenugreek, and fennel. Use panchphoron in oil to start any Bengali-style vegetable dish for an authentic base flavour.
5. Soft paneer and cheese dishes: A pinch of kalonji in the marinade or topping for paneer tikka or baked paneer adds an unexpected savoury depth. It also works beautifully sprinkled on homemade paneer before pressing.

How to Buy and Store Kalonji
ODM Nigella Seeds are carefully cleaned to remove dust and impurities, so you get only the bold, deeply black seeds with their natural essential oils intact. Look for seeds that are completely black (not grey or faded) — faded colour usually means old stock with diminished flavour.
Store kalonji in an airtight glass jar away from heat and moisture. They hold their flavour well for up to a year when stored properly. A small jar in your tadka lineup will transform dishes you have been making for years.
If you want to explore more of the whole spice range, ODM Carom Seeds (Ajwain) and ODM Fenugreek Seeds (Methi Dana) are two other underused spices worth keeping close at hand. Together with kalonji, they form the backbone of some of the most distinctive tadkas in Indian cooking.
