Mahi Mahi Ceviche with Coconut Dressing

This is another one from Michele Cranston (Marie Claire Easy cookbook). You're not supposed to cook the mahi mahi but I panicked and cooked mine since it frozen.

Ingredients
500g firm white fleshed fish, skinned and boned (I used mahi mahi)
3 limes, juiced
100ml coconut cream (I used light coconut milk - couldn't find the cream at Safeway)
1 tsp grated fresh ginger
1/2 tsp ground turmeric
1 tsp sugar (I used stevia)
1 tbsp finely chopped coriander
2 scallions, sliced (I used 4 because I love scallions)
Cooking oil (if you want to cook the fish)

Preparation
1. Cut fish into bite-size pieces (I didn't). Marinate fish pieces in lime juice in the fridge for 2 hours.
2. Optional (I did this because I panicked about frozen fish): drain and cook fish in frying pan - about 3 mins each side. I just used coconut oil to cook.
3. In a separate bowl, mix coconut, ginger, turmeric, sugar, coriander and stir to combine.
4. Drain fish (If you didn't cook it) and add to the coconut dressing. Sprinkle on scallions.
