South India's pepper-forward soup blend
The blend that makes rasam — black pepper dominant, coriander base, with dried curry leaves. Less complex than sambar powder, more direct.
Rasam powder is simpler and more direct than sambar powder — it is designed specifically for a thin, peppery soup rather than a thick dal-based sambar. Black pepper is the primary flavour rather than coriander — piperine provides the sharp, immediate warmth that is rasam's signature. The blend also contains toor dal (toasted), which provides subtle body when ground into the powder. Like all South Indian spice blends, curry leaves are dried and included.
| Quantity (makes ~50g) | Spice — and its role |
|---|---|
| 3 tbsp | Black pepper dominant — the defining flavour Primary flavour |
| 2 tbsp | Coriander seeds mild base Base — balances pepper |
| 1 tbsp | Cumin seeds earthy Base |
| 1 tbsp | Toor dal (split pigeon pea) body Toasted dal — gives body |
| 1 tbsp | Dried red chillies secondary heat Heat |
| 1 tsp | Fresh curry leaves dried Essential aroma |
| ½ tsp | Turmeric colour Colour — add after roasting |
| ¼ tsp | Asafoetida depth Depth — add after roasting |
Toast toor dal 3–4 minutes until golden. Dry curry leaves 1–2 minutes until brittle. Remove both.
Toor dal in rasam powder is primarily a textural and body contributor — the roasted starch thickens the rasam water very slightly, giving it more presence. Black pepper's piperine is the heat compound in rasam — it produces a sharp, fast warmth different from capsaicin's sustained burn.
Roast black pepper, coriander, cumin and chillies. Cool. Grind everything including toor dal, curry leaves, turmeric and hing.
