Bangus - Inun-unan Recipe

You can use any kind of fish for the isda inun-unan recipe depending on your preference, but the budget-conscious prefer to make it with milkfish, galunggong, and other inexpensive yet equally good-tasting fish varieties. As for the vegetables, ampalaya (bitter gourd), which surprisingly doesn’t make the soup bitter at all, and eggplant frequently make the list of ingredients.

Fish Cooked in Vinegar

Rabbitfish, however, are used for this recipe as its flesh is soft and tasty. The only problem is you can’t eat the belly part of the rabbitfish as it tends to taste bitter if not properly cleaned. Bangus (milkfish), on the other hand, makes a great fish for this recipe, especially the head and belly part (not so much for the body and tail part as it’s full of bones). It tastes so good that it takes twice the amount of time to finish eating the upper half of the fish than usual because people love to savor its taste by sucking the meat (especially around the eyes and the brain) until only the bones are left.
