Rinse the rice until the water runs clear. Put in a small saucepan with 250ml (1 cup) water, cover and bring to a simmer over medium heat. Reduce the heat to low and cook for 12 mins or until tender and the water is absorbed. Turn off the heat and stand, covered, for at least 5 mins.
Step 2 — Prep ingredients
Meanwhile, halve the zucchini and carrot lengthwise, then slice. Slice the fish into strips.
Step 3 — Start curry
Heat a drizzle of oil in a medium saucepan over medium-high heat. Add the curry paste and cook, stirring, for 1 min or until fragrant.
Step 4 — Add fish
FISH OPTION Add the coconut milk and 80ml (⅓ cup) water and bring to a simmer. Add the zucchini, carrot and fish. Reduce the heat to medium and cook, stirring occasionally, for 4 mins. Add the peas, cover and bring to a simmer. (It's important it doesn't boil or the coconut milk may separate.) Cook, uncovered, for 2-3 mins until the fish is cooked through.
Step 5 — Finish curry
Remove the pan from the heat, add half the fish sauce* and ½ tsp sugar to the curry and stir to combine. Taste, then season with salt.
Step 6 — Get ready to serve
Fluff the rice with a fork. Divide the rice and fish curry among bowls to serve.
