Tilapia Fillets Cooked With Slices Of Raw Mango

Tok MaachThis dish is to die for! In Rangoon (Burma/Myanmar) this was made with whole Topshe maach (Mango Fish). I used filleted fish pieces which is not the same at all! Mum used to make it with Topshe maach, potatoes and wedges of green mangoes. A Bangladeshi market opened up in our neighbourhood and I found frozen raw mango in packages. I used about 10 slices in a pound of fish and it came out too tangy. Perhaps the unsweetened, dried mango slices in Mango Fish are a better bet or the amount of raw mango slices should be cut down drastically and ground to a paste before adding to the gravy.

2 lbs. Tilapia fillets, cut in pieces (medium sized whole fish is better)1/2 tsp. turmeric powdersalt to taste
2 Tbsp. vegetable oil
2 russet potatoes, peeled and cut lengthwise in long pieces2-3 slices raw/green mango, ground to a paste 
     or 1 pkg. dried, unsweetened mango slices
