First, peel the onion. Cut it in half and then into 1-inch-thick wedges. Next, slice the red and green bell peppers into 1-inch thick strips. Set aside for later.
Season the kingfish with ¾ teaspoon of adobo on both sides. Make sure the entire fish is well seasoned. Then, in a large pot, add 2 cups of oil over medium-high heat. Fry the fish for 5 minutes on each side. Place it on a shallow plate and set aside for later.
While the fish is frying, prepare the escabeche. In a medium saucepan over medium-high heat, add the oil, vegetables, black pepper, bay leaves, and 1 teaspoon of adobo. Cook for 5 minutes. Once cooked, turn off the heat, add the garlic paste, and vinegar, and stir.
Pour the escabeche marinade mix over the fried fish. Serve and enjoy!
Notes
You can prepare this recipe in advance and serve it later.
The longer the fish remains in the escabeche marinade, the more intense its flavor will have.
The fish will keep in the refrigerator for up to 4 days.
