Escabeche de cebolla is a traditional Yucateco pickle made by placing red onions in red wine vinegar with peppercorns, oregano, cumin, and garlic. Once prepared, the pickle should be refrigerated for at least four hours before serving.
Escabeche de cebolla is beloved in Yucatán because the onions soak up the flavor of cumin and oregano. It is recommended to serve escabeche de cebolla with fresh seafood and grilled meat dishes, or use it in tacos and sandwiches.
