I first had tuna ceviche at a seafood restaurant in Tijuana, Baja California, Mexico. It reminded me of tuna tartare or tuna poke. Here’s my take on this Japanese-inspired, Mexican food.
INGREDIENTS:
Two 6 to 8-ounce sushi-grade tuna filets, cut into 1/2-inch cubes (available at a Japanese supermarket or seafood section of any supermarket)
Juice of 1 to 2 limes
1/2 teaspoon Dijon mustard
2 to 3 tablespoons extra-virgin olive oil
1/2 to 1 teaspoon chopped jalapeno pepper
1/2 red onion, peeled and chopped into 1/4-inch pieces
1/2 cup finely-chopped carrot
1/2 cup finely-chopped cilantro
1/2 teaspoon salt
ground black pepper, to taste
1 package corn tostadas
DIRECTIONS:
1. In a large glass or porcelain bowl, combine the tuna, juice from one lime, Dijon mustard, olive oil, 1/2 teaspoon jalapeño pepper, red onion, carrot, cilantro, salt and ground black pepper.
2. Toss all ingredients together; taste.
3. If more lime juice, jalapeño and/or salt are needed, add a little more; taste once more.
4. If needed, adjust seasonings again.
5. Serve the tuna ceviche immediately on corn tostadas.
6. The tuna ceviche can be made a few hours ahead on the same day, covered and refrigerated.
