I like flounder because it’s so thin and “cooks” quickly. If flounder isn’t available, red snapper, halibut, or cod are great too! You can add whatever flavorings you want, but my favorite is Serano, cilantro, and a mix of lime/orange juice. You could add pineapple or serve it with some avocado. I don’t recommend mixing avocado into the ceviche because it tends to get mushy, and the dish won’t save as well. It’s great to bring to a party or as an easy lunch, dinner, or tapas dish. Serve with fried plantains or any chip of your choice!
