Ingredients

Scale

1 lb sushi-grade tuna
2 large ripe avocados (use 3–4 if smaller)
0.5 cup ruby radishes, thinly sliced
2 Tbsp soy sauce (or tamari for gluten-free or soy-free)
1 Tbsp toasted sesame oil
1 Tbsp fresh lime juice
1 tsp grated fresh ginger
garnish options (black or white sesame seeds, fresh microgreens, or chopped chives)

Instructions

Prep Tuna: Using a very sharp knife, dice 1 lb (450g) sushi-grade tuna into small, even 0.25-inch (0.6 cm) cubes. Keep it chilled in a bowl in the refrigerator until ready to mix.
Make Dressing: In a medium bowl, whisk together 2 Tbsp (30ml) soy sauce (or tamari), 1 Tbsp (15ml) toasted sesame oil, 1 Tbsp (15ml) fresh lime juice, and 1 tsp (5g) grated fresh ginger until well combined and fragrant.
Combine Tuna and Dressing: Gently fold the diced tuna into the prepared dressing using a silicone spatula. Do not overmix, as this can mush the tuna and compromise its delicate texture; aim for just coated.
Prepare Avocado Fan: Halve 2 ripe avocados, carefully remove the pit, and peel the skin. Place each avocado half flat-side down on a cutting board, then thinly slice each half lengthwise (aiming for consistent 0.125-inch or 0.3 cm slices), and gently fan them out on individual serving plates.
Assemble and Garnish: Spoon the tuna mixture neatly onto the fanned avocado on each plate. Garnish generously with thinly sliced ruby radishes, a sprinkle of black or white sesame seeds, and fresh microgreens or chopped chives for elegant presentation.
Serve Immediately: For best flavor and texture, serve this dish within 10 minutes of assembly while all components are perfectly chilled. Store any unserved components separately in airtight containers in the fridge.

Notes

For a spicier kick, add a pinch of red pepper flakes or a dash of sriracha to the dressing. For a lighter, crunchier version, serve with sturdy cucumber slices instead of crackers. Avoid using non-sushi grade tuna for raw consumption due to food safety. Do not overmix the tuna as it can become mushy. Ensure all ingredients are well-chilled for optimal taste and texture.
