A Beginner’s Guide to Indian Spices: What to Buy and How to Use Them

When I first moved to London, I stood in front of the spice shelf in a supermarket and felt oddly lost. Back home in Pune, my aai’s spice box, a round steel tin with small bowls inside, was always within arm’s reach, and I had learned to use it just by watching. Now I had to decide what to buy and how much. If you are new to Indian cooking, the long list of spices can feel just as confusing. This guide covers the essentials you actually need, how to use them and how to keep them fresh.

Whole spices versus ground spices

Whole spices, such as cumin seeds, mustard seeds and cardamom pods, keep their flavour for much longer because their aromatic oils stay locked inside. Ground spices are convenient but lose their fragrance faster. A good rule is to buy whole spices when you can and grind them as needed, and to buy ground spices in small quantities that you will finish within about six months.

Ten spices to start with

You do not need dozens of jars to cook good Indian food. These ten will cover most of the recipes on GetToKnow.

• Turmeric powder (haldi): gives dishes a golden colour and a warm, earthy flavour. A little goes a long way.
• Cumin seeds (jeera): nutty and aromatic, used whole in tempering and ground in spice mixes. They are the heart of Jeera Rice.
• Coriander powder (dhania): mild, citrusy and slightly sweet, it thickens and rounds out gravies.
• Kashmiri chilli powder: gives a vivid red colour with only gentle heat, which is why it appears in tandoori dishes and curries.
• Mustard seeds (rai): they pop in hot oil and add a sharp, nutty flavour to South Indian dishes such as Masala Dosa filling.
• Garam masala: a warming blend of spices such as cardamom, cinnamon, cloves and black pepper, usually added near the end of cooking.
• Green cardamom (elaichi): sweet and floral, used in chai, desserts and rice dishes.
• Black pepper: adds gentle heat and depth to both savoury dishes and masala chai.
• Asafoetida (hing): a pungent resin used in tiny pinches in lentils and vegetable dishes, where it adds a savoury, onion-like depth.
• Dried fenugreek leaves (kasuri methi): crush them between your palms over creamy gravies at the end of cooking for a restaurant-style aroma.

What is tempering (tadka)?

Tempering is one of the most important techniques in Indian cooking. You heat oil or ghee, add whole spices such as mustard seeds, cumin and curry leaves, and let them sizzle for a few seconds until they release their fragrance. The hot, spiced oil is then poured over dal, rice or vegetables, or used as the base for a dish. Watch the pan closely, because spices can burn in seconds and turn bitter. If a spice darkens too fast, lower the heat or lift the pan off the burner.

Toast to wake up the flavour

Dry-roasting whole spices in a pan for a minute or two, until you can smell them, brings out their aroma and makes them easier to grind. Let them cool before grinding in a mortar or a spice grinder. Do this only with whole spices, and never leave the pan unattended.

How to store your spices

• Use airtight jars: glass or steel containers with tight lids protect spices from moisture and air.
• Keep them cool and dark: avoid storing jars above the cooker, where heat and steam shorten their life.
• Label and date them: write the purchase date on each jar so you know what to replace.
• Buy small amounts: a small pack from a busy shop is fresher than a giant bag that sits for a year.
• Trust your nose: if a spice has lost its smell, it has lost its flavour.

Where to buy them

Indian grocery shops usually have fresher stock and better prices than the spice aisle of a large supermarket, and they often sell whole spices in bulk. If you do not have one nearby, many online shops deliver. Look for packs with a recent packing date.

Start cooking with them

The easiest way to learn is by making a few dishes. A warm, simple Kanda Poha teaches you tempering with mustard seeds and curry leaves. A Rajma Chawal shows how ground spices build a gravy. And a slow-cooked Dal Makhani finishes with kasuri methi for that unmistakable aroma. If you want to plan a whole meal, my guide to the Indian thali shows how different dishes and flavours balance on one plate.

Start small, taste as you go and trust your nose. Soon your own spice box will feel as natural as the one I grew up with.
