Have you heard of ceviche? It’s a popular dish in many Latin American countries that uses lemon or lime juice is used to “cook” raw fish.

Done well, ceviche means fish with a perfectly firm but tender texture, a bright citrus taste, and a pure fish flavor that you might associate with the freshest sashimi.

I just got back from an amazing trip to Costa Rica where I ate ceviche literally every single day. I ate it at a couple of high end restaurants as well as at countless bars and roadside sodas (family-run restaurants).

My favorite meal was in a little bar in the tiny surfer village of Estarillos Oeste. Here, the ceviche came with grilled corn, avocado, and local sea bass. This was the inspiration for the recipe I’m making here!

Ceviche is just all about timing. If you make your ceviche too far in advance, the fish will first become too firm and then begin to turn to mush as the citrus denatures the proteins. But if the fish hasn’t marinated in the citrus juice for long enough, it will still be a little gelatinous.

Ceviche is perfect when the outside of the fish is an opaque white, but the inside is still just a smidge translucent.

I prefer to cut my fish for ceviche into good-sized chunks, about 1/2-inch wide. With pieces this size, I find the fish reaches the right texture after about 20 to 30 minutes.

If I’m in a hurry, I sometimes cut the chunks of fish smaller to cut the “cook” time down to 15 to 20 minutes instead.

It might take you a few tries to find your perfect texture! Start tasting the fish around the 15-minute mark, and taste every few minutes until your fish tastes good to you.

Also, although “cooking” fish in this way changes its texture and flavor, it’s still raw from a food safety standpoint. It is extremely important to find a fishmonger you trust and who will sell you high quality fresh fish.

And one note on the corn for this recipe: When sweet corn is in season, it really only needs a few minutes to steam before it’s perfect. If you have the time, I think the extra step of throwing it on the grill or under the broiler for a couple of minutes is worth it for the charred flavor, but if you’re hurried, you can definitely skip that step.
