Spicy Tuna Tartare on Cucumber Rounds is a refreshing and elegant appetizer that's perfect for summer gatherings or any occasion where you want to impress your guests. The combination of spicy, creamy tuna and crisp cucumber creates a delightful contrast that is both satisfying and light.
Sushi-grade tuna is the star of the show, offering a tender, melt-in-your-mouth texture. Make sure it's fresh and high-quality, as it will be served raw. Mayonnaise provides a creamy base that binds the tartare together, while Sriracha sauce introduces the signature spicy kick. A dash of sesame oil adds a nutty aroma and depth, and soy sauce brings a savory umami note. Freshly grated ginger and lime juice lend a bright, zesty contrast to the richness. Green onions contribute a mild, savory flavor and a bit of crunch. Finally, cucumber rounds serve as a refreshing, crunchy platform for the tartare, while a sprinkle of sesame seeds and cilantro elevate the presentation and add extra flavor.
These spicy tuna tartare bites pair wonderfully with a crisp white wine or a light, refreshing cocktail. They're perfect as a starter for a sushi-themed dinner or alongside other light appetizers like edamame or seaweed salad. For a more substantial spread, consider serving them with steamed rice or as part of a larger platter of seafood delights.
Begin by preparing the spicy aioli. In a medium bowl, combine the mayonnaise, Sriracha sauce, sesame oil, soy sauce, grated ginger, and lime juice. Mix until you have a smooth, well-blended sauce. This will serve as the flavorful base for your tartare.
Next, gently fold in your finely diced sushi-grade tuna. Take your time and mix it gently to ensure the tuna is evenly coated with the spicy aioli without mashing it. Season the mixture with a little salt and pepper. It's a good idea to taste and adjust the seasoning to your liking at this point.
Now, arrange the cucumber slices on a serving platter. Make sure they're spread out nicely, as each will be topped with a portion of the tuna tartare. Carefully place a spoonful of the tuna mixture on each cucumber round, ensuring that each one has a generous serving.
Finish by garnishing each piece with a sprinkle of sesame seeds and a touch of chopped cilantro. This not only enhances the flavor but also adds a pop of color, making the dish as attractive as it is tasty.
