I first had red prawn ceviche in a small restaurant in Madrid where the chef brought it to the table in a shallow bowl with a ladle of corn water poured over it at the last second. Spanish red prawns cut into pieces and marinated in the juice of four limes until they turned opaque. Mixed with finely chopped red onion, fresh cilantro, and the corn water, a broth made by boiling sweet corn and straining the liquid. Diced ripe avocado folded in at the end.
The corn water is the move that separates this from every other ceviche. It is mild and sweet, almost like a light broth, and it pools around the prawns and avocado. The lime does the cooking. The cilantro and onion do the seasoning. The avocado makes each bite rich and cool. It is a dish that tastes like the ocean and a cornfield at the same time.
Tips for Making Red Prawn Ceviche with Corn Water
Marinate the prawns in lime juice for fifteen minutes
The lime juice chemically cooks the prawns. Fifteen minutes is enough for bite-sized pieces to turn from translucent to opaque. Longer than thirty minutes and the texture gets rubbery.
Use fresh lime juice, not bottled. Fresh juice has a brighter acidity that bottled cannot match.
Make the corn water ahead
Boil the sweet corn in water until the liquid is flavoured and slightly sweet. Strain and chill.
The corn water should be cold when you add it to the ceviche. Warm liquid would start cooking the avocado and wilting the cilantro.

Frequently Asked Questions
What are Spanish red prawns?
A variety of large prawns from the Mediterranean, prized for their sweet flavour and firm texture. Any large, fresh prawns or shrimp work as a substitute.
Can I skip the corn water?
You can, but you lose the sweet, brothy element that makes this recipe different. Without it, you have a standard lime ceviche, which is still good but less interesting.
How far ahead can I make this?
Make the corn water a day ahead. Marinate the prawns and assemble the ceviche no more than thirty minutes before serving. The avocado browns and the prawns overcook in the lime acid.

1 gram of sweet corn??? Is this correct?
