Place the onions in a medium saucepan and pour in enough water to cover. Bring to a boil and remove from the heat. Strain and set the onions aside. Combine all the remaining ingredients in the saucepan. Bring to a boil, reduce to a simmer, and cook 10 minutes. Add the blanched onions and simmer an additional 10 minutes. Transfer the mixture to a container, cover and refrigerate at least a day before serving. Pickled onions will keep in the refrigerator up to a month. Makes 5 1/2 cups
In a large bowl, combine fish and enough lime juice to cover. Allow to marinate for 20 minutes. Drain fish, reserving 1/4 cup of lime juice. Combine fish with remaining ingredients and reserved lime juice to taste and stir gently to combine. Chill thoroughly. Serve in a chilled martini glass, garnished with plantain chips or tortilla chips, pickled red onions and slices of avocado. Serves 4.
