Bharadwaj's biryani approach codifies the partial-cooking principle with specific targets: the rice must be cooked to exactly 70% before layering. This is not intuitive — the par-cooked rice is clearly not ready to eat; it has a firm, slightly chalky centre. But in the sealed dum environment, this underdone rice will absorb the spiced steam from the meat layer below and finish to perfect separate-grain texture. Fully cooked rice in a dum becomes mushy; under-70% rice remains chalky even after dum.
- **The par-boiling water:** Heavily salted — as salty as sea water. The salt seasons the rice during par-boiling. Under-salted par-boiling produces bland finished rice regardless of the spiced meat layer. - **Whole spices in the boiling water:** Bay leaf, cardamom, cloves — their aromatic compounds extract slightly into the cooking water and season the rice at the grain level. - **The 70% test:** Bite a grain at the critical moment. The exterior should be fully cooked and translucent; the very centre should have a tiny, barely-perceptible white dot of uncooked starch. When this dot is visible under scrutiny but almost gone, the rice is at 70%. - **Saffron milk:** Saffron steeped in warm milk — the saffron's colour (crocin) and aroma (safranal) distribute through the milk. Drizzled over the top rice layer before sealing, it provides both colour (golden streaks through the white rice) and aroma. - **The dum seal:** Dough pressed around the pot rim, or a heavy lid weighted with a pot of water. The seal must hold for the full dum time — any steam escaping is carrying aromatic compounds with it. Decisive moment: The 70% test — and the decision to remove the rice from the boiling water at exactly this point. Rice continues cooking from residual heat for 60–90 seconds after being drained. The rice that looks 70% in the pot is 75% by the time it is spread in the baking vessel. Pull slightly early. Sensory tests: **The bite test at par-cooking:** Remove one grain, bite through the centre. Correct: exterior fully translucent, very centre shows a minute white point under close inspection. Incorrect (overdone): no white centre at all. Incorrect (underdone): significant resistance and white core visible without scrutiny. **Saffron milk smell:** The milk after saffron steeping should smell distinctly floral and slightly honey-medicinal — safranal's characteristic aroma. Poor-quality saffron (or saffron substitute/dye) produces no smell, only colour.
