Understanding Heat & Your Vessels

Indian cooking uses heat more dynamically than almost any other cuisine — from the fierce blast that makes mustard seeds pop in a tadka to the gentle simmer that develops a korma over 45 minutes. Understanding what your stove and pan are actually doing at each temperature is the foundation that makes every other technique work correctly.

Most cooking failures trace back to heat mismanagement — the burnt tadka, the watery curry, the tough dal. Understanding heat means understanding why: spices release flavour compounds at specific temperatures, onions caramelise through the Maillard reaction above 150°C, and proteins set at different temperatures depending on the dish.

The Method — Step by Step
How to do it correctly
1
Start with a cold pan
Most Indian cooking starts in a cold pan — add oil first, then heat. This distributes heat evenly and prevents hot spots that burn spices.
🔬 The Leidenfrost effect: water in food splatters more violently into very hot oil. A gradually heated pan reduces this.
⚠ Never add spices to smoking oil — they burn immediately at smoke point temperatures above 200°C.
2
Learn your stove's heat levels
Mark or memorise: Low (gentle simmer), Medium-Low (tadka), Medium (onion cooking), Medium-High (bhuno), High (boiling). Indian recipes assume you know these intuitively.
🔬 Different hobs reach different temperatures at 'medium' — gas hobs run hotter than electric at the same setting.
3
Choose the right vessel
Heavy bottom pan (kadai or Dutch oven) for curries — distributes heat evenly. Tawa for flatbreads — conducts heat rapidly for direct contact cooking. Pressure cooker for dal — traps steam to raise boiling point above 100°C.
🔬 Thin pans concentrate heat at the base — causing hot spots that burn masala while leaving edges undercooked.

Common Questions
What temperature should oil be for tadka?
For most tadkas: medium heat until a mustard seed dropped in sizzles immediately without burning — approximately 160-170°C. Too cool and spices don't release flavour; too hot and they burn before you add the next ingredient.
Why does my pan have hot spots?
Thin-bottomed pans concentrate heat at the burner contact points. Use a heavy kadai or Dutch oven for even heat distribution. Alternatively, use a heat diffuser between burner and pan.
What is the difference between a simmer and a boil?
A simmer is 85-95°C — small bubbles rising gently from the base. A boil is 100°C — vigorous bubbling throughout. Most Indian curries are simmered not boiled — boiling at too high heat toughens proteins and evaporates flavour compounds.
Why does food stick to my pan?
Usually temperature-related: food sticks when placed in a pan that isn't hot enough to create the steam barrier (Leidenfrost effect) that prevents adhesion. Heat the pan and oil properly before adding food.
What pan should I use for Indian cooking?
A 24-28cm heavy-bottomed kadai or Dutch oven for most curries and rice dishes. A flat tawa for breads. A pressure cooker for dal and pulses. These three cover 90% of Indian cooking.
