For me, the only way to eat tuna is raw, and not just sushi or sashimi. I’m not a fan of what most restaurants do: serving tuna seared on the outside and rare on the inside. You can tell the quality of the tuna just isn’t there. It usually needs to be drowned in soy sauce to have any taste at all.
So getting my tuna fix often means I’ve got to prepare something at home.
If you’re paranoid about parasites, tuna is probably the safest fish to eat raw. I buy my tuna wild-caught and frozen from reputable sources.
Technically, fish needs to be frozen at a temperature of -4°F (-20°C) or below for 7 days, for parasites to be killed. In the United States, this is required by law of all fish served at sushi restaurants, with tuna being the only exception.
Most marinades or ceviches use lemon or lime. I enjoy the freshness of grapefruit, and it really works here. This recipe was literally created by opening my fridge and pantry, and grabbing whatever looked good.
1 lb. excellent quality raw tuna
juice of 1 grapefruit
1 teaspoon grapefruit zest
2 teaspoons low-salt soy sauce
1/2 teaspoon wasabi powder
1/2 teaspoon hot pepper sauce (I use Frank’s Red Hot)
1/2 teaspoon black pepper
1/2 teaspoon sesame oil
1/4 teaspoon sea salt (I use Fleur de Sel)
1 tablespoon chopped scallions, green part only
sesame seeds (optional)
cubed avocado or plain guacamole
If I’m starting with frozen tuna, I allow it to thaw just enough so I can cut it into small cubes easily. I place the cut tuna on paper towels to soak up excess moisture, and keep it in the fridge.
In a bowl, I combine all the other ingredients, except the sesame seeds and avocado. I add the tuna to the bowl, and mix everything carefully, putting it back in the fridge to marinate for an hour.
When I’m ready to serve, I place the tuna on a plate. (If it’s very runny, I use a slotted spoon.) I top it with a sprinkling of sesame seeds and serve with fresh cubed avocado, or even plain guacamole.
