1In a bowl, combine fish fillets, vinegar, and calamansi juice. Let it marinate in the refrigerator for at least 30 minutes.
2Add ginger, red onion, chili, salt, and pepper to the marinated fish. Mix well.
3Chill the Kinilaw na Isda before serving. Serve cold as an appetizer or with steamed rice as a main course.
For that extra kick, you can add more chili if you want it spicier. Make sure the fish is fresh for the best Kinilaw experience!
