- 200 g king oyster mushrooms, halved lengthwise, cut chunky

- 1.5 L hot vegetable stock (or water)
- 2-3 scallion greens, finely sliced, for garnish Brown mushrooms: Heat pot with a generous film of oil.
Fry shiitake, chestnut, and king oyster mushrooms in batches until golden. Drain each batch, reserving oil.

- Season base: Stir in garlic, thyme, cayenne, black pepper.
Cook 1 min until fragrant. Gradually add stock, stirring to avoid clumps. Season lightly with salt.

20-25 min for flavours to meld.

Notes
- Extra oil (about 10% more than the flour weight) offsets mushroom absorption.
- For extra umami, add 1-2 tsp soy sauce with the garlic.
- Stop roux earlier (milk chocolate colour) if you prefer a milder, less smoky gumbo.
