Cook's notes

Oven temperatures are for conventional; if using fan-forced (convection), reduce the temperature by 20˚C. | We use Australian tablespoons and cups: 1 teaspoon equals 5 ml; 1 tablespoon equals 20 ml; 1 cup equals 250 ml. | All herbs are fresh (unless specified) and cups are lightly packed. | All vegetables are medium size and peeled, unless specified. | All eggs are 55-60 g, unless specified.

Instructions

You will need a very sharp large knife and a kitchen blowtorch; alternatively, place tuna under a hot grill.

Chilling time 3 hours

To prepare tuna, place it on a chopping board. Wipe tuna with a clean damp tea towel. Using a very sharp large knife, trim edges, cutting the tuna in a single motion, drawing the knife back towards you smoothly. Holding the tuna with one hand, cut into 5 blocks, again using a single slicing action; do not saw the fish. Using fish tweezers (available from chef’s shops, homeware shops and fish markets), remove the bloodline from each block of tuna.

Place 1 tuna block on a plate, cover with a clean damp tea towel and refrigerate until ready to plate the raw version. (If it’s warm, refrigerate the 4 tuna blocks and remove from the fridge as required.)

To make soy-cured tuna, combine soy and mirin in a small bowl. Using a very sharp large knife, cut 1 tuna block into 4 even cubes using a single slicing action starting from the heel of the knife, down to the point, drawing the knife towards you. Immerse in soy mixture for 5 minutes or until flesh becomes darkened from the soy. Drain. Place on a plate, cover with a clean damp tea towel and refrigerate for up to 3 hours until needed.

To make blow-torched tuna, place another tuna block on a wire rack set over an oven tray. Using a blowtorch, cook each side of tuna until flesh just starts to char. Immediately refresh in iced water. Place on a plate, cover with a clean damp tea towel and refrigerate for up to 3 hours until needed.

To make tuna blanched in oil, fill a saucepan one-third full with oil and heat over medium heat to 180°C (or until a cube of bread turns golden in 10 seconds). Insert 2 skewers through centre of 1 tuna block to hold its shape, and immerse in oil for 20 seconds or until flesh turns light golden. Immediately refresh in iced water. Remove skewers, place on a plate, cover with a clean damp tea towel and refrigerate for up to 3 hours until needed.

To make tuna blanched in water, bring a saucepan of water to the boil. Immerse tuna for 3 seconds or until flesh just turns evenly opaque, then drain and refresh in iced water. Place on a plate, cover with a clean damp tea towel and refrigerate for up to 3 hours until needed.

When ready to serve, cut the raw, blow-torched, blanched and fried tuna into 4 even cubes. Arrange on a plate with soy-cured tuna. Spoon a little extra virgin olive oil over each piece of tuna, then garnish soy-cured tuna with fried garlic chips and red chilli; raw tuna with yuzu zest and chopped pickled jalapeños; blow-torched tuna with black sesame seeds and salmon roe; blanched tuna with a little light soy, wasabi and lemon zest; and fried tuna with a coriander leaf and finely shredded ginger. Serve immediately.
