Contramar is my favorite restaurant in Mexico City. It is this 20-year-old restaurant in the Roma district of CDMX. Anytime a friend is traveling to Mexico city and they ask for recommendations, I always say to dine at Contramar. It is like no other restaurant. It is a seafood focused Mexican restaurant that uses limes, spices and chiles on all their seafood. I usually go for lunch as it is almost impossible to get a dinner reservation!

This Tuna Tostada is a lime and soy sauce marinated tuna on a tostada and garnished with a chipotle aioli, avocado, and scallions. If you are making this delicious appetizer, you have got to chase it down with a Paloma or a light beer. It is to die for. You should definitely research your local fish markets and get the freshest fish possible. The flavors will all come together!

  • 5–7 Tostadas
Chipotle Aioli
  • 1 egg yolk
  • 1 tablespoon lemon juice
  • 1 clove garlic
  • 1/2 cup vegetable oil
  • 1/4 cup chipotle chiles in adobo sauce from a can, drained
  • 1 teaspoon kosher salt

  • 4 limes, juiced
  • 1 tablespoon sesame oil
  • 1/2 cup soy sauce
  • 2 tablespoons chopped scallions
  • 1 avocado, sliced
  • Everything but the bagel seasoning

Make the chipotle aioli. Place egg yolk, lemon juice, garlic, chipotle chilies and salt in a food processor or blender and blend. Slowly add the oil and blend until smooth.
Prepare the tuna. Cut the sashimi grade tuna into slices. Make sure to cut against the fibers/lines of the tuna. Place slices of tuna in a large mixing bowl and add the juice of 4 limes, sesame oil and soy sauce. Stir and let it marinate for 5 minutes.
Assemble the Tostadas. Spread the chipotle aioli on a tostada. Place 2-3 slices of the marinated tuna on the tostada and garnish with the avocado, scallions and everything but the bagel seasoning.
  • You can let the lime marinate in the tuna longer if you want the fish to cook more.
