Refreshing flavours with a spicy zing—and, at 15 g per serving, a whopping load of protein—come together in this classic ceviche. Rockfish, often sold under the name Pacific snapper, is high in selenium—an 85 g serving provides 44 percent of the recommended daily value of the mineral, which has a role in preventing infection and cell damage, as well as in the proper functioning of the thyroid. Rockfish is also a good source of healthy omega-3 and omega-6 fats.
Ceviche tips
Keep an eye on the fish while it is “cooking” in the lime/lemon juice; 30 minutes is usually optimum to achieve a “just cooked” texture. You can extend that to an hour or more, but after about 2 hours, you’ll find that the texture will change and become “overcooked.” Waiting to add the tomatoes and avocado just at serving time keeps flavours fresh and distinct.
Per serving:
Cut fish into 1/2 in (1.25 cm) cubes and place in single layer in rectangular glass dish fitted with lid. Juice limes and lemon to yield about 3/8 cup (90 mL) and pour over fish. Place in refrigerator and allow lime/lemon juice to “cook” the fish for about 30 minutes.
Place sliced onion and serrano pepper overtop of fish and allow to marinate for 10 to 20 minutes more.
To serve, combine ceviche with grape tomatoes and heap onto individual plates or shallow bowls, placing a few slices of avocado alongside. Season with salt and pepper and garnish with chopped cilantro.
