FAQ

Can I use light coconut milk?

Yes, but the soup will be less creamy. To keep body, simmer a few extra minutes to reduce slightly, and finish with a small splash of full-fat coconut milk or a drizzle of coconut cream if you have it.

What fish works best?

Firm, mild white fish like cod, halibut, snapper, or haddock hold up well. Tilapia works too, but cut it into larger chunks and simmer gently so it doesn’t break apart.

How do I make it spicier?

Add more curry paste, sliced fresh chilies, or a pinch of chili flakes at the end. Taste as you go so the heat doesn’t overpower the lime and coconut.

Is there a non-fish version?

Use tofu cubes or chickpeas for protein. Add them after the broth simmers, and cook until warmed through. The flavors still shine.

Can I freeze this soup?

It’s not ideal. Coconut milk can separate and fish can become mushy after thawing. If you must, freeze the broth without fish, then add fresh fish when reheating.
