Bright, citrus-forward, and impossibly fresh, this no-cook ceviche is the kind of dish that makes a serious impression with very little effort. Sushi-grade white fish — sea bass, halibut, or flounder all work beautifully — gets cubed and submerged in a punchy blend of fresh lime and lemon juice, which gently denatures the proteins and turns the fish silky and opaque without a single burner being turned on. Red onion, jalapeño, cilantro, and a touch of ground cumin round out the flavor, giving you heat, brightness, and depth in every bite. Creamy diced avocado is folded in at the end so it stays intact and lush rather than turning into mush. The whole thing comes together in under 30 minutes, making it a genuinely impressive appetizer or light meal that feels far more restaurant-worthy than the prep time suggests. For anyone navigating spice sensitivities, this recipe keeps things clean and straightforward — every ingredient is whole and identifiable, with no spice blends or seasoning packets that might sneak in unwanted additions. Scoop it up with tortilla chips or eat it straight from the bowl; either way, it disappears fast.

Use only sushi-grade or sashimi-grade fish labeled safe for raw consumption — this recipe relies entirely on acid marination, not heat, to denature the fish proteins. Cut the fish into ½-inch cubes and place in a large mixing bowl.
Add the lime juice, lemon juice, and kosher salt to the bowl and stir to coat every piece of fish. The fish should be fully submerged in the citrus juice; add a splash more lime juice if needed.
