The most important decision you’ll make about your ceviche happens before you ever step into the kitchen: where and how you buy your fish. The difference between good ceviche and transcendent ceviche is almost always the quality of the seafood.
What Does “Sashimi-Grade” Actually Mean?
Here’s a secret: “sashimi-grade” is not a regulated term in the United States. It’s a marketing term that fishmongers use to indicate fish that they consider suitable for raw consumption — but there are no federal standards governing its use.
What it really signals is that the fish has been: (1) handled with exceptional care from boat to counter, (2) kept at consistently cold temperatures, and (3) is very fresh — ideally landed within the last 48 hours.
The Five Senses Test
Smell: Fresh fish smells like the ocean — clean, slightly briny. Any fishy, ammonia-like, or sour smell is a red flag. If you can smell it through the paper wrap before unwrapping, don’t buy it.
Eyes: For whole fish, the eyes should be clear, bright, and convex (bulging slightly). Sunken, cloudy eyes = old fish.
Flesh: Press the flesh gently with one finger. It should spring back immediately. If the indentation stays, the fish is past its prime.
Color: White fish should be pearl-white or translucent. Tuna should be deep ruby-red without any browning at the edges. Salmon should be bright orange-pink.
Surface: The flesh should be moist but not slimy. Any sliminess indicates bacterial growth.
Best Fish for Ceviche by Region
Not all fish cure equally. The best options depend on your region and what’s freshest locally.
