10g onion
½ garlic clove
2,5ml (½ tsp) fresh ginger
3g fine salt

Celery and lime water (second stage)
100ml fresh lime juice (from 1kg limes)

100g ice cubes
salt, to taste
2g pickled jalapeños, finely chopped
To serve
mixed herb salad (parsley, chives and fennel)
5 x 80g fresh tuna steaks

Instructions

For the crispy onions, peel the onions and slice into rings on a mandoline or gravity slicer. Add salt and sugar to the onions and allow to rest, 20 minutes. Squeeze out all of the water, allow to dry and fry until crisp at 180°C. Place on paper towel and season with the maltodextrin salt mixture/sea salt to taste.

For the avocado purée, place the avocado, lemon juice and salt in a blender and blitz on a high speed until smooth. Adjust seasoning if needed.

For the first stage of the celery and lime water, place all of the ingredients, except the coriander stems, in a blender and blitz to a smooth purée. Add the coriander stems and leave to marinate, 1 hour, before removing the coriander. Refrigerate until ready to use.

For the second stage of the celery and lime water, add the lime juice, base and ice cubes to a blender and blitz, 1 minute. Strain through a sieve into a glass bowl and adjust seasoning. Add the jalapeños. Cover and refrigerate, 5 minutes before use.

For the tuna, slice the steaks lengthways to your desired thickness. Eat the tuna raw or sear it on a griddle pan or over a grill, 3 seconds per side.

To serve, spread the avocado purée on a plate, lay the tuna atop, sprinkle over the crispy onions, mixed herb salad and a drizzle of the celery water.
