How to Make Ahi Tuna Tostadas
Follow these step by step instructions to make this recipe for Ahi Tuna Tostados.
Step 1: Marinate Tuna
Toss your tuna into the freezer and let it firm up for 10-15 minutes. This will make it exponentially easier to cut. Meanwhile, mince your shallot and jalapeño and toss them into a medium sized bowl, add a good pinch of sea salt and a couple turns of fresh pepper.
Once the ahi tuna is firm, cut it into 1/4 inch cubes and add it to the bowl. Pour over the lime juice and stir to incorporate everything. Cover with plastic wrap and let it marinate in the fridge for at least 20 minutes, or up to 3-4 hours.
Step 2: Make Elote
To make the chipotle mayo; in a small bowl or food processor, mix together the sour cream, mayo, adobo sauce and pepper, lime juice, and salt. Or use a store bought spicy mayo.
Fill a large pot with water and bring to a boil. Husk your corn, and once the water is rolling, add the corn and cook for 5 minutes until the corn is bright yellow. Remove with tongs and transfer to a hot cast iron skillet and char all sides. Alternatively, you can also cook the corn on the grill, simply place husked and oiled corn on the grill and cook, turning occasionally, until they are nicely charred on all sides. 10-15 minutes.
Once the corn is safe to handle, use a sharp knife to cut the charred corn off its cob. In a small bowl, mix together the chipotle mayo, ancho chili powder, salt, pepper, and the corn. Set aside
Step 3: Fry Tortillas
If you are using store bought fried tortillas, skip this step.
In a medium cast iron skillet, heat a cup of canola oil over medium heat. Fry your corn tortillas one at a time. Bubbles should form almost immediately once in the hot oil. Use metal tongs to flip and prevent the tortillas from contorting to much. Fry for 15-20 seconds on each side, or until they are golden brown. Remove with tongs to a paper towel lined plate.
Step 4: Assemble, Garnish, & Enjoy!
Place the fried tortilla on a plate and scoop a couple tablespoons of the corn mixture onto it. Then layer a couple healthy scoops of the marinated tuna on top of the corn. Sprinkle the cheese over that, and garnish with cilantro, lime juice, and flaky sea salt. Enjoy!
