Pinamalhan is a dish from the Philippines, the Ilonggo version of Paksiw (fish cooked in Vinegar). Pinamalhan is an Ilonggo method of preparing fish by cooking it in vinegar, soy sauce, ginger, garlic and a host of other spices and seasoning. It is actually a Paksiw but a dry version.
Pinamalhan is made by putting all ingredients in the pan and cook until dry.
Pinamalhan is from the Ilonggo word "mala" meaning dry, hence its name.
