This recipe presents a vibrant Tuna-Avocado Ceviche, featuring fresh ahi or albacore tuna "cooked" in Key lime juice, then mixed with crisp cucumber, red onion, creamy avocado, and aromatic cilantro. The dish is elevated by the smoky, spicy depth of Salsa Macha. It's a quick, refreshing, and flavorful appetizer or light meal, perfect for serving with tostadas.
For this ceviche, prioritize sushi-grade tuna for safety and optimal texture. Precision in dicing the tuna, cucumber, onion, and avocado ensures a cohesive presentation and even distribution of flavors. Always use freshly squeezed Key lime juice; its bright acidity is vital for 'cooking' the tuna and balancing the rich Salsa Macha. Introduce the avocado just before serving to maintain its vibrant green color and creamy texture, preventing oxidation. The curing time for tuna ceviche should be brief—just enough for the lime juice to lightly firm the fish, typically 5-10 minutes, to avoid a tough consistency. Serve immediately with crisp tostadas for textural contrast. The Salsa Macha provides a deep, smoky heat; adjust the amount to taste.
