Bistek Bangus is a Filipino fish dish where fish is first pan fried then served with a sauce made out of soy sauce, calamansi and onions.
Bistek is a cooking method in the Philippines where meat is first pan fried then served with a sauce made out of soy sauce, calamansi and onions. Usually meats like beef and pork is used in this method but a popular fish in the Philippines called milkfish can also be used.
I think this dish just enforces the fact that Filipinos do love sour dishes. This is quite sour especially when someone likes putting lots of calamansi, the sourness gives the dish pleasant taste as it cuts out the grease of the pan fried fish while giving it a fresh taste. Like the original bistek recipe this is best consumed with freshly cooked jasmine rice but unlike the original I recommend eat this the traditional way using your hands to get the full experience.
