Method

Heat oil in a heavy-bottomed pot over medium heat. Add the onion, sliced thin, and cook until translucent — this takes roughly 4 minutes. Add the garlic and ginger (minced fine) and stir constantly for 90 seconds until the raw edge disappears and the aromatics release their sharpness. This base, called the tadka in bhutanese-cuisine, is your flavour scaffold.

Dust in the turmeric and fry for 30 seconds — no longer, or it catches and turns bitter. You'll smell the shift from raw powder to warm spice; that's your signal to move on. Add the whole green chillies (keep them intact at this stage) and the mushrooms (quarter them; slicing leaves too much surface area and they disintegrate). Toss everything together and cook for 2 minutes over medium heat, stirring to coat everything in oil. The mushrooms will begin to release their liquid.

Pour in 800 ml water and bring to a rolling boil — don't timid this with a gentle simmer from the start. The vigorous boil extracts flavour from the chillies and creates bhutanese-cuisine the characteristic mouthfeel of the broth. Once boiling, reduce to a steady simmer (bubbles breaking the surface every second or so) and cook for 20 minutes. The chillies will soften and the broth will take on a faint green tint from their skins.

Add the tomato, chopped into rough chunks, and the salt. Taste the broth now — it should be peppery and clean, with the chillies still holding their shape but yielding to a knife. Continue simmering for another 5 minutes. If the chillies still feel fibrous when you bite one, give it another 3 minutes; the goal is a slight give without collapse.

Finish with fresh coriander leaves scattered across the surface just before serving. Serve in bowls, hot. Diners can eat the chillies whole and manage the heat themselves, or split and deseed them at the table for less intensity.
