Cut the raw fish into bite-size chunks, and sprinkle salt onto the fish, leave it for 3 to 5 minutes.

Mix with vinegar and salt in a bowl, and put it in the refrigerator.

Slice the onion and apples, dice tomatoes. (Put the sliced onions in some water.)

When the fish becomes white, wash it with water and drain the water from the fish using kitchen paper.

Squeeze lemon over the vegetables and fish, add salt, pepper and coconut milk.
