What is inun unan?

Inan unan is a simple dish where fish and vegetables like okra, bitter gourd, eggplant or string beans are stewed in vinegar and spices.

Unlike Paksiw na Isda version, where pork is often used, inun unan only uses fish.

Almost any fresh fish can be used can be used for this dish but tuna, tilapia, butterfish or milk fish are most commonly used.

  • Any local fish (scaled, gutted, sliced into halves, and seasoned with salt and pepper)
  • Any local vinegar (store-bought ones are okay too, but won’t smell as good)
  • Crushed garlic (lots and lots of it, i.e. for a dozen medium-sized fish, use 1 big head of garlic)
  • Sliced onions (lots and lots of it, maybe 2-3 bulbs)
  • Crushed ginger (lots and lots, like maybe a third of your palm)
  • Salt
  • Black pepper (crushed and corns)
  • 1 tbsp ginamos (fermented fish if available)
  • Cayenne peppers (siling espada, optional, or bird’s eye chilies if you want to increase the spiciness)
  • Young mango leaves (1 per piece)
  • Used cooking oil (oil used to fry pork is preferred)


  • Mix everything in a bowl, except for the fish, mango leaves, cayenne peppers, and used cooking oil.
  • Adjust the taste to your liking.
  • Add the fish and gently mix with your hand for 3 minutes or so.
  • Wrap each fish with mango leaves and place in a thick pan or clay pot (include some of the spices if you like).
  • Pour all the marinade on top, including the cayenne peppers.

Cooking tips

  • If possible, don’t cook this dish in a metal pot, as the vinegar develops a metallic flavor. Use a clay pot or a casserole dish.
  • Almost any fish can be used can be used for this dish, but tuna, tilapia, butterfish, or milk fish are most commonly used.
  • Once the vinegar marinade boils, do not mix it. Just allow it to simmer. This will ensure that the fish absorbs as much of the flavor as possible.
  • The proportion of vinegar and water is usually 1 measure of vinegar to 2 measures of water. If a stronger inun unan is preferred, the proportions can be reversed.

Inun-Unan Recipe ( Visayas Paksiw)

In a country that spans more than 7 000 islands, each region has developed its own local variations of popular dishes.

Inun unan is a Visayan (Visayas is one of the 3 major regions of the Philippines) version of the fish paksiw dish, a typical everyday dish made from fish simmered in a vinegar-based broth.

What pot should you use to cook inun unan?

In many Filipino homes there is a special clay pot used for cooking inun unan (to avoid the metallic taste the vinegar develops when cooked in a metal pot).

Usually, the inun unan is served directly from the clay pot and leftovers are kept in it. If you do not have a clay pot, an ordinary casserole dish is a good alternative.

This is a very simple version of inun unan. This recipe uses a basic combination of vinegar, ginger, spices and fish.

What do you serve with inun unan?

Serve with warm white rice and bagoong which is a popular fish sauce in the Philippines.

The sauce is made with anchovies or other varieties of small fish that have been cleaned, cured with salt and allowed to ferment for several months.

What is the origin of inun unan?

The name inun unan comes from the Visayan word un-un which means to “stew with vinegar, salt and spices”.

Before the advent of refrigeration, pickling fish in vinegar was one of the easiest ways to preserve fish for a couple of days.

Substitutions and variations on traditional inun unan

There are a lot of substitutions or variations that you can add to this dish.

The most traditional inun unan uses only fish and no vegetables. Other recipes add vegetables like eggplant, okra or green beans to the fish. Some recipes do not add any water to the vinegar.

The traditional inun unan is spiced only with ginger. But you can also add garlic, chilies, onions and peppercorns. Palm sugar is sometimes added to balance out the acidity of the vinegar.

Bangus or milkfish is traditionally used for inun unan but you can substitute the milkfish for bullet tuna, butterfish or tilapia.

Although traditionally served with hot steamed rice, sometimes scrambled eggs are added to the rice, together with some of the broth.
