ChefXi OfficialCrispy, golden-fried polenta squares serve as the pedestal for sashimi-grade tuna tossed in a spicy Thai-inspired dressing. A soulful bridge between the Italian countryside and the bustling markets of Bangkok.
Cut the chilled, firm polenta into 2-inch squares, about 1/2 inch thick. Pat them completely dry with a paper towel to ensure maximum crispness.
Moisture is the enemy of a good crust. Dry them thoroughly!
In a chilled glass bowl, combine the diced tuna, minced shallots, lemongrass, Thai chili, lime juice, fish sauce, and olive oil. Gently fold to combine. Keep this mixture in the refrigerator until the moment of serving.
The acidity of the lime will 'cook' the tuna if left too long, so mix this right before you fry the polenta.
Heat the vegetable oil in a heavy-bottomed skillet over medium-high heat. Once shimmering, fry the polenta squares in batches until golden brown and crispy on both sides, about 3-4 minutes per side.
Drain the crispy polenta on a wire rack for 1 minute to maintain the crunch.
Never drain on paper towels; it traps steam and makes the bottom soggy.
Place the warm polenta squares on a serving platter. Top each square with a generous spoonful of the tuna mixture. Garnish with torn basil leaves and a tiny pinch of sea salt.
The key to this dish is the temperature contrast between the warm, crispy polenta and the cold, vibrant tuna. Ensure your oil is hot enough (375°F) to sear the polenta quickly without making it greasy. Respect the lineage of the corn by using a high-quality, stone-ground variety.
