Marinate fish with 2 cloves of garlic (crushed) , 1 tablespoon vinegar, salt and freshly ground pepper.
Leave for 30 minutes or longer in the fridge. If you want a crispier result hang the fish to dry for about an hour (I didn't because I don't want to stand around swatting the flies that I know would swamp in if I were to hang it out).
Depending on the size of fish, use 3-5 tablespoon oil to shallow fry until crisp at the sides.
Delicious with any pickles or salad (especially bambangan) and rice.
