Gently bruise the lemongrass, kaffir lime leaves, and chillies (if using) to release their aroma.
Step 2
Heat coconut oil in a large saucepan. Add the bruised aromatics, followed by garlic, ginger, galangal, and red curry paste. Sauté for 1–2 minutes until fragrant.
Step 3
Pour in the vegetable stock. Cover and let simmer on medium-low heat for 7–8 minutes, allowing the flavours to infuse.
Step 4
Add mushrooms, spinach, lemon zest, and coconut milk. Simmer uncovered for 2–3 minutes. Stir in the spring onions, lemon juice, and salt. Add tofu cubes and gently simmer for another 3–4 minutes.
Step 5
Serve hot, with extra lemon wedges on the side for brightness.
