Steps
- Soak the sliced red onion in a bowl of cold water for 10 minutes. Drain and set aside.
- In the meantime, bring a small saucepan of water to a gentle simmer over medium-low heat. Blanch the prawns for 1 minute or until nearly cooked through. Drain and refresh under cold water, then chop into 1cm pieces.
- In a ceramic or glass bowl, combine the kingfish, chopped prawns, garlic, chilli, and coriander. Season to taste, then add lime juice and 5 ice cubes to almost cover the mixture. Incorporate one-third of the drained onion and stir to combine; the lime juice will turn a whitish hue after a moment. Taste the ceviche and adjust seasonings as needed.
- Remove the ice cubes and stir in the extra virgin olive oil. Garnish with the remaining onion and serve with rye bread croutons and lime wedges.
