Ceviche Basics
The acid in lime juice transforms the texture of raw fish from translucent and soft to opaque and firm. Mastering ceviche is less about a formal recipe and more about managing temperature and timing.
Cold is your best friend
Keep your fish in the coldest part of the refrigerator until the exact moment you are ready to cube it. Work over a bowl nestled in an ice bath to maintain food safety and structural integrity.
- Sharp chef's knife
- Glass or stainless steel mixing bowl
- Citrus juicer
- Fine mesh strainer
What goes in.
- 1 lbfirm white fish (such as sea bass, snapper, or halibut), skinless and boneless
- 1 cupfreshly squeezed lime juice
- 1/2red onion, shaved paper-thin
- 1serrano or habanero chili, seeded and minced
- 1/4 cupfresh cilantro leaves, torn
- 1 tspkosher salt
The ten-minute rule
The fish is ready when the edges of the cubes turn white and opaque, usually within 10 to 15 minutes of contact with lime juice. Leaving it longer results in a chalky, dry texture that masks the natural sweetness of the fish.
The method.
Prep the fish
Cut the fish into uniform 1/2-inch cubes. Use a sharp knife and a single slicing motion to keep the edges clean; avoid sawing, which tears the flesh.
Season the base
Place the cubed fish in a chilled glass bowl. Add the salt and minced chili, tossing gently to coat evenly.
Add the acid
Pour the lime juice over the fish. Ensure the liquid just barely covers the cubes. Stir once, then let it rest in the refrigerator.
Check for doneness
Watch for the color change. As soon as the cubes are opaque throughout but still springy to the touch, drain half of the lime juice to stop the process.
Fold and serve
Gently fold in the shaved red onion and cilantro. Plate immediately while chilled.
Other turns to take.
Coconut infusion
Add a splash of unsweetened coconut milk to the lime juice to mellow the acidity.
Tropical addition
Fold in finely diced mango or pineapple just before serving for a contrast to the chili heat.
When it doesn't go to plan.
Discard any dark red or grey parts of the fish flesh, as they have a strong, fishy flavor.
Always use fresh lime juice; bottled versions contain additives that prevent the proper denaturation of proteins.
If the red onion is too sharp, soak the slices in ice water for 10 minutes and pat dry before adding.

Can I use frozen fish?
Yes, provided it is high-quality, 'sushi-grade' fish that was flash-frozen at the source.
Why did my ceviche turn mushy?
The fish was likely left in the lime juice too long, or the fish pieces were too small and disintegrated under the intensity of the acid.
