Set a heavy pan over medium heat and add the coconut oil. When the oil shimmers, add the cardamom, cloves, cinnamon, bay leaf, peppercorns, and curry leaves, and bloom for no more than 30 seconds — so the heat coaxes the fragrance out of each spice while the oil carries that fragrance into every part of the dish. The spices are ready when they are audibly popping and the oil smells sharply, warmly aromatic.

Add the pearl onions and stir to coat them in the spiced oil, so each onion is slicked with fat and absorbs the bloom rather than sitting beside it. Cook over medium heat for 3 to 4 minutes until the onions are softened and translucent at the edges; they should offer no resistance when pressed.

Add the potato, carrot, and French beans, then pour in the second-extract (thin) coconut milk and season with salt. No turmeric, no red chilli, no colouring agent of any kind enters the pot, because the pale, near-white broth is the visual and flavour identity of ishtu — any colour agent changes the dish fundamentally. Stir once to combine.

Bring to a gentle simmer and cook, partially covered, for approximately 15 to 20 minutes, keeping the heat low so the thin coconut milk stays creamy rather than turning grainy from a rolling boil. The vegetables are ready when the potato cubes yield without resistance to a knife point and the beans have lost all crunch entirely.

Remove the pan from the heat and extract and discard the whole spices and the curry leaves. Pour in the first-extract (thick) coconut milk and stir gently to incorporate, off the heat entirely, so the rich extract stays smooth and the broth holds its pale, cohesive colour — sustained heat after this point causes it to split. The finished stew should be smooth, fragrant, and almost white.
