Alpha Gal Friendly No-Cook Ceviche
Bright, citrus-soaked, and loaded with creamy avocado, this ceviche is the kind of dish that tastes like a vacation. Sushi-grade white fish — sea bass, halibut, or flounder — gets cubed and submerged in a punchy mix 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. For anyone navigating alpha-gal syndrome, this recipe is a natural fit: it's built entirely around seafood, fresh produce, and citrus, with zero mammalian meat or hidden animal-derived additives to worry about. Thinly sliced red onion, jalapeño, cilantro, and a whisper of cumin round out the flavor so every bite has heat, brightness, and depth. The avocado folds in at the end to add richness and keep things feeling indulgent without complicating the ingredient list. Serve it straight from the bowl with tortilla chips and it disappears fast — this one is genuinely hard to stop eating.

Instructions
- 1
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.
- 2
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.
