Serves 2
Pickled cucumber
In a small saucepan, combine the vinegar, 125 mL water, sugar and salt, then cook until the sugar has dissolved, taking care not to let it boil.
Remove from the heat and allow to cool for 10 minutes.
Pour the pickling liquid over the cucumber and leave to rest for at least 2 hours.
Soy dressing
Place all ingredients into an upright blender except the grapeseed oil and process well.
With the blender running, slowly pour in the oil to emulsify the dressing.
Avocado and tuna
Mash the avocado with the milk and push it through a fine sieve.
Process the wakame finely in an electric spice grinder.
To serve
Arrange the tuna on a plate and place small spoonfuls of avocado on each piece of fish.
Drizzle over 2 tsp of the soy dressing.
Season the tuna lightly with sea salt.
Place one piece of pickled cucumber on each piece of tuna.
Top each with a slice of radish.
Sprinkle the whole dish with wakame powder.
