In a pot, add vinegar and water and bring to a boil. Turn the stove off and add all the ingredients for the sauce.
Take the pot off the stove and let the ingredients sit in the hot water with the lid on.
After the Escovitch sauce has cooled down, transfer to a mason jar or a glass container with a lid.
Escovitch fish
Clean the fish in a mixture of vinegar and water; pat dry with absorbent paper. Combine salt and black pepper and use to season the fish. Cover and allow to marinate.
Heat skillet over medium flame and add vegetable oil. Add crushed garlic and fry to release flavour. Add fish and fry until lightly browned on both sides; drain on absorbent paper.
Arrange on a serving platter and drizzle with Escovitch Sauce.
