Chettinad Chicken Dum Biryani

Chettinad's layered dum biryani — bone-in chicken marinated in freshly ground kalpasi-marathi mokku masala and cooked dum-style with seeraga samba rice. Darker, drier, and more intensely spiced than Ambur or Hyderabadi biryani — this is the biryani of the Nattukotai Chettiar trading families.

🧺 Ingredients

• 1 kg chicken, bone-in, cut into 8–10 pieces
• 1 cup thick curd (yoghurt), whisked smooth
• 2 tbsp ginger-garlic paste (fresh ground: 8 garlic + 2-inch ginger)
• 1.5 tsp red chilli powder
• 1 tsp coriander powder
• ½ tsp turmeric powder
• 1 tsp salt
• 1 tbsp coriander seeds
• 1 tsp fennel seeds (sombu)
• 1 tsp cumin seeds
• 1 tsp black pepper, whole
• 4 dried red chillies
• 1 piece cinnamon (4 cm)
• 5 green cardamom pods
• 5 cloves
• 2 star anise
• 1 marathi mokku (dried kapok flower — Chettinad signature spice)
• 1 piece kalpasi (stone flower / dagad phool — 2 cm)
• 1 small piece javitri (mace — kaapu pattai)
• 2.5 cups seeraga samba rice (the short-grain aromatic variety essential to this biryani — NOT basmati)
• 5 cups water
• 1 tsp salt
• 1 tbsp ghee
• 2 green cardamom pods
• 1 piece cinnamon (2 cm)
• 2 cloves
• 1 bay leaf
• 3 large onions, thinly sliced (for caramelising + for gravy)
• 3 medium tomatoes, finely chopped
• ¼ cup fresh mint leaves (pudhina)
• ¼ cup fresh coriander leaves
• 4 green chillies, slit
• 4 tbsp sesame oil (gingelly) + 2 tbsp ghee
• 2 tbsp maida (plain flour) + water (stiff dough, for sealing the lid)
• OR 2 sheets of aluminium foil + a heavy weight
• Parboiling to exactly 60–70%: this is the most critical technical step. Under-cooked rice will be raw after dum; over-cooked rice will be mush. At 60–70%, the grain bends but doesn't break, and there is a visible chalky core at the centre when you press it.
• The dum seal: even a tiny gap allows steam to escape — the steam is what cooks the rice's remaining 30%. A failed seal = undercooked biryani.
• Low, diffused heat for dum: direct gas flame at even medium heat will burn the bottom within 10 minutes. The tawa diffuser is essential.

👩‍🍳 How to make Chettinad Chicken Dum Biryani

1. Dry roast the Chettinad masala (medium heat): Roast each spice group in sequence in a dry pan — dried red chillies first (1 minute, turning until blistered and dark). Add coriander, fennel, cumin, and pepper together (2 minutes, stirring, until they darken 1–2 shades and smell deeply toasted). Add cinnamon, cardamom, cloves, star anise, marathi mokku, kalpasi, and javitri (1 minute — they darken quickly, pull off heat promptly). Cool completely on a plate. Grind to a slightly coarse powder in a mixie or spice grinder. This masala powder can be made ahead and stored.
2. Marinate the chicken (no heat, minimum 2 hours): In a large bowl, combine chicken pieces, whisked curd, ginger-garlic paste, red chilli powder, coriander powder, turmeric, salt, and 2 tbsp of the Chettinad masala powder. Mix thoroughly — coat every piece. The curd should turn orange-red. Cover and refrigerate minimum 2 hours, ideally overnight.
3. Parboil the seeraga samba rice (medium-high heat): Wash the rice in 5 changes of water until water runs clear (seeraga samba has more starch than basmati). Soak for 20 minutes. In a large pot, bring 8 cups of water to a rolling boil with 1.5 tsp salt, whole spices (cardamom, cinnamon, cloves, bay leaf), and 1 tbsp ghee. Add soaked and drained rice. Cook uncovered on medium-high for 7–8 minutes — the rice should be 60–70% cooked (firm with a tiny white chalk-like core when pressed between fingers). Drain immediately in a large colander. Spread on a wide plate and fan or cool rapidly — this stops the cooking process.
4. Caramelise the onions (medium-high heat): Heat 3 tbsp sesame oil + 2 tbsp ghee in a heavy-bottomed biryani pot (or wide Dutch oven). When oil shimmers, add two-thirds of the sliced onions. Fry on medium-high, stirring every 3–4 minutes, for 20–22 minutes until they are deep golden-brown and caramelised — not burnt, but a rich mahogany colour. Remove half these caramelised onions with a slotted spoon and set aside (for layering later). Leave the other half in the pot.
5. Build the chicken masala (medium heat): In the same pot with the remaining caramelised onions, add the marinated chicken pieces (along with all the marinade). Fry on medium-high for 8–10 minutes, turning the chicken pieces, until the marinade coats the chicken and the oil separates around the edges. Add the chopped tomatoes. Cook 7–8 minutes until the tomatoes break down completely and the masala is thick. Add remaining 1 tbsp Chettinad masala powder. Add slit green chillies. Stir and fry 2 more minutes.
6. Test the chicken: Pierce a thick piece — juices should run clear or barely pink. The chicken should be 80% cooked at this stage — it will finish in the dum. Add ½ cup water if the masala looks very dry and sticking. Taste — the gravy should be assertively spiced, salty enough to season the rice. Adjust salt.
7. Layer the biryani (no heat): In the same pot, spread the chicken masala evenly across the bottom. Scatter half the reserved caramelised onions, half the mint leaves, and half the coriander leaves over the chicken. Pile the 60% cooked seeraga samba rice evenly over the top. Add the remaining caramelised onions, mint, and coriander as the top layer. Drizzle 1 tbsp ghee over the rice.
8. Seal and dum cook (very low heat, 25 min): Roll the maida dough into a long rope. Press firmly around the rim of the pot to seal the lid completely — no steam should escape. (Alternatively: double-layer heavy-duty foil over the pot, then weight with a heavy lid or stone.) Place the pot on the lowest possible heat. If using gas, place a tawa (flat griddle) under the pot — this diffuses heat and prevents the bottom from scorching. Cook on this very low dum for exactly 25 minutes. After 25 minutes, you will smell the biryani through the seal — deeply aromatic.
9. Open and rest: Break the seal (or remove foil) and open the lid away from you (steam will rush out). The rice on top should be fully cooked — fluffy and separate grains. If the top layer is still slightly raw, replace the lid (without sealing) and cook on low 5 more minutes. Once done, turn off heat and rest covered (without the seal) for 10 minutes.
10. Mix and serve: Using a wide flat spoon, gently mix the top rice layer with the bottom chicken layer — a folding motion, not a stirring motion. Do not over-mix (the Chettinad biryani is traditionally served "mixed but not mashed"). Serve hot with onion-mint raita, Chettinad potato fry, and a hardboiled egg.
