Our Traditional Island Sauce (Mojo Isleño) is a tomato-oil based sauce that is mainly cooked with onions for a delicious sweet tart flavor.  It is primarily used as a topping or dipping sauce for our fried red snapper (chillo frito).



  • ½ cup of extra virgin olive oil
  • 2 cups of homemade tomato sauce or 2 cans (8 ounces each) of tomato sauce
  • 20 pimiento stuffed green olives, cut into halves
  • 2 tablespoons capers
  • ½ tablespoon lite salt or to taste
  • 1½ cups water (room temperature)
  • 2 tablespoons red wine vinegar
  • 1-pound sliced onions
  • 2 to 3 bay leaves.


  1.  In a saucepan, heat ½ oil over medium heat.
  2.  Add the remaining ingredients into saucepan and stir until well blended.  Cook for medium heat for 5 to 10 minutes.
  3.  Reduce heat to low and simmer for approximately 40 to 60 minutes or until the volume is reduced, creating a thicker sauce.  Stir occasionally.
  4.   Serve as a topping or dipping sauce for our Fried Red Snapper.


This sauce can also be served with a variety of seafood.
