Flavour Building
Chettinad, from the Chettinad region of Tamil Nadu in southern India, is one of the most intensely spiced cuisines in the world. What distinguishes it from other South Indian cooking is the use of freshly ground spice blends (never pre-made powders), the prominent role of kalpasi (stone flower lichen), marathi mokku (dried flower pods), and star anise alongside the standard South Indian spice repertoire, and a cooking technique that dry-roasts every spice individually before grinding. The chicken Chettinad that appears on restaurant menus worldwide is a pale shadow of the real thing — which should contain 15-20 different spices, each treated with specific attention.
Using pre-ground spice powders — the entire point is freshly ground. Substituting vegetable oil for sesame oil — the nutty roasted sesame flavour is integral. Under-spicing — Chettinad food should be intensely aromatic and hot. Omitting kalpasi and marathi mokku — without them it's generic South Indian, not Chettinad. Using curry powder — there is no single Chettinad curry powder, each dish has its own specific blend.
Every spice is dry-roasted separately to its optimal point — cumin and fennel get light toast, black pepper and coriander get medium, dried chillies get dark. Kalpasi (stone flower) is the signature ingredient — it adds a musky, earthy depth impossible to replicate. Marathi mokku provides a floral note. All are ground together into a fresh paste with shallots, garlic, ginger, and sometimes poppy seeds or coconut. The paste is fried in sesame oil (gingelly oil) — not any other oil — until the raw smell disappears and the oil separates. Tamarind provides the sour element. Curry leaves are used lavishly — handfuls, not a few leaves.
