Kinilaw is a traditional Filipino dish that features raw seafood or meat marinated in vinegar or citrus juice, like calamansi or lime. It's often mixed with onions, tomatoes, chili peppers, and various seasonings to create a refreshing and tangy flavor.
In a bowl, combine the sliced fish or seafood with the vinegar and calamansi or lime juice. Make sure the fish is fully submerged in the liquid. Let it marinate for about 20-30 minutes to "cook" the fish in the acidity of the vinegar and citrus juice.
After marinating, drain the liquid from the fish or seafood. You can choose to discard the liquid or reserve a small amount to mix in later for additional flavor.
Add the sliced onions, diced tomatoes, minced chili peppers, and ginger to the fish or seafood. Mix everything together gently.
Season with salt and pepper to taste. Adjust the amount of chili peppers according to your preferred level of spiciness.
Let the Kinilaw sit for a few minutes to allow the flavors to meld together. You can refrigerate it for an hour or two if you prefer a colder serving.
When ready to serve, garnish with chopped fresh cilantro for an added touch of freshness and aroma.
