Ingredients

For the Pepper-Crusted Tuna

450 g fresh tuna steak cut into elegant bite-sized cubes
2 tbsp olive oil
2 tsp smoked paprika
1 tsp garlic powder
1 tsp onion powder
1 tsp cayenne pepper
1 tsp dried thyme
1 tsp sea salt
¼ tsp freshly ground black pepper

For the Avocado Crème

1 perfectly ripe avocado
120 ml sour cream
1 tbsp fresh lime juice
½ tsp garlic powder
Sea salt and black pepper to taste

Method

Preparing the Tuna

Begin with the tuna—fresh, firm, and vibrant in colour. Slice into neat, bite-sized cubes, keeping each piece uniform for an even, delicate cook. Set aside, allowing the fish to come slightly to room temperature—this ensures a more refined sear and a tender centre.

Blending the Blackening Spice

In a small bowl, combine the smoked paprika, garlic powder, onion powder, cayenne, dried thyme, salt, and black pepper. Stir until the mixture is evenly perfumed and richly coloured. This is where the dish finds its depth—a warm, aromatic blend that will form that signature, gently charred crust.

Searing the Tuna

Heat a wide skillet over medium-high until just shy of smoking. Add the olive oil, then lightly coat the tuna cubes in the spice blend, ensuring each piece is beautifully covered. Lay them into the pan in a single layer, allowing space between each cube.
Sear briefly—around 1–2 minutes per side—until the exterior is deeply coloured and fragrant, while the centre remains soft and blush-pink. Remove from the heat promptly to preserve that delicate texture.

Creating the Avocado Crème

Meanwhile, turn to the avocado. Mash until smooth and velvety, then fold in the sour cream, lime juice, and garlic powder. Season thoughtfully with salt and black pepper. The result should be light, creamy, and quietly bright—a cooling counterpart to the warmth of the spice.
With each element prepared, all that remains is to bring them together—where contrast, texture, and balance truly come into their own.

Notes

Choose with Care

Begin, always, with quality. Seek out tuna that is vibrant in colour and firm to the touch—freshness here defines both flavour and texture. When possible, source from a trusted fishmonger; it’s a quiet investment that pays off beautifully on the plate.

Season to Your Taste

The spice blend should feel balanced, not overpowering. If you prefer a gentler warmth, soften the cayenne slightly. If you lean toward something bolder, a touch more heat—or even a pinch of chilli flakes—can deepen the character of the dish. It should feel personal, never rigid.
