It is typically prepared by sautéing onions until they become soft and caramelized, then adding vinegar, sugar, and other flavorings to create a sweet and tangy relish. Onion relish is known for its rich, savory-sweet flavor and is often used as a topping or accompaniment for a variety of dishes. It can be served with burgers, sandwiches, hot dogs, sausages, grilled meats, cheese platters, and more.
