Tuna Tostada

Crispy tortillas meet smoky salsa macha, creamy chipotle aioli, and buttery slices of sushi-grade tuna, with heat, acid, crunch, and richness in every bite.

Why You'll Love Tuna Tostada

Who doesn't love a crispy, creamy, spicy, citrusy tuna tostada layered with housemade chipotle aioli, salsa macha, and crunchy fried leeks? Inspired by Contramar and zhuzhed by TanyaShaby - this may be the best bite I've had in 6 months.

Tips and Tricks

• Use a thermometer for frying oil to hit perfect crispness on both tortillas and leeks.
• Prep salsa macha and aioli ahead to make assembly quick and stress-free.
• Slice tuna cold straight from the fridge to keep it clean and thin.

Variations

• Swap tuna for salmon or hamachi
• Add thinly sliced radish or cucumber
• Drizzle with sweet soy glaze or citrus ponzu

Substitutions

• Use mayo + sriracha instead of chipotle aioli
• Use sunflower oil if you're out of avocado oil
• Swap Greek yogurt base for aioli if avoiding raw egg

Best served with

• Crisp lager or michelada
• Paloma or mezcal cocktail
• Chilled cucumber soup
• Pickled vegetables

How to Store Leftovers

• Salsa macha will keep up to 5 days in a sealed container at room temp. Aioli keeps 3 days refrigerated. Tuna and leeks should be stored separately in the fridge and used within 24 hours. Always assemble tostadas fresh for best texture and presentation.

3. Add chopped chipotle chiles and kosher salt. Blend another 30 seconds.
4. Transfer to a container and refrigerate for up to 3 days.

For the salsa macha

1. In a saucepan, heat avocado oil with garlic and nuts over medium heat until garlic is golden (6-8 minutes).
2. Use a slotted spoon to transfer garlic and nuts to a heatproof bowl. Strain if needed.
3. Return oil to the pan and reheat. Add chiles and fry for 30 seconds until brick-red. Remove from heat.
4. Transfer chiles to the garlic/nut bowl. Let cool 5 minutes.
5. Add sesame seeds to the hot oil (off heat) and set aside to toast.
6. In a food processor, purée the cooled garlic/nut/chile mix with bay leaves, oregano, and salt.

8. Store salsa macha in an airtight container at room temp for up to 5 days.

2. Cover fried tortillas with a kitchen towel to keep warm.
3. Return oil to 325°F. Fry leeks for about 5 minutes until golden but still slightly green. Drain on paper towels.
