Ceviche, tiradito and sashimi

Ceviche, tiradito and sashimi get used as though they were three words for the same plate. They are not. The fish may be identical and the difference is entirely in what is done to it, which is the sort of distinction that sounds pedantic until you order the wrong one.

Here is what actually separates them, and, because it is the honest thing to say up front, which of the three we serve and which we do not.

Ceviche: the fish is cooked, just not with heat

Ceviche is Peruvian and it is the oldest of the three ideas. Raw fish is cut into cubes and dressed in citrus, and the acid denatures the protein in much the same way heat would. The flesh turns opaque and firms up. It is cooking by chemistry rather than by fire.

The marinade matters more than the fish does, and in Peru it has its own name: leche de tigre, tiger milk. Lime, chilli, onion, the juices that come out of the fish, sometimes a little of the fish itself blended in. It is served in the bowl, and drinking what is left is not bad manners.

Ours is sea bass with mango, passion fruit, pickled onion, coriander and tiger milk. The mango and passion fruit are the Brazilian hand on a Peruvian dish, and they are doing real work rather than decorating: sweetness against acid stops a ceviche becoming a mouthful of lime. The onion is pickled rather than raw for the same reason.

Tiradito: sliced like sashimi, dressed like ceviche

Tiradito is the youngest of the three and the most specific. The fish is not cubed, it is sliced thin, the way sashimi is. There is no onion. The sauce is not a marinade the fish sits in, it is poured over at the moment of serving, so the flesh stays raw rather than turning opaque.

It exists because of Japanese immigration to Peru. Japanese cooks working with Peruvian ingredients kept the knife work and the respect for raw fish and took the acid and the chilli, and the result got a name of its own. It is the clearest single dish in what is now called Nikkei cooking.

We do not serve tiradito. It is worth saying plainly rather than letting you look for it: there is ceviche on the menu and there is sashimi, and the space between them is not currently filled.

Sashimi: nothing is done to it at all

Sashimi is Japanese and is the most exposed of the three, because there is no acid and no sauce to hide behind. It is fish, cut well, and that is the whole dish. Everything depends on what came in that morning and on the knife.

Ours are four pieces each. Salmon with spicy passion fruit and sliced jalapeno. Sea bass with pineapple, fresh coriander and baby celery. Both are cut thick rather than thin, which is a choice: a thicker slice keeps its temperature longer and gives you something to chew against the fruit.

Strictly, the tropical element beside them is a step away from sashimi in the Tokyo sense. It sits next to the fish rather than on it, so the fish stays raw and unmarked, which is closer in spirit to tiradito than to anything else on the menu. If tiradito is what you were after, these are the nearest thing we have, and they are a small plate rather than a commitment.

If you would rather not choose, the chef's sashimi combo is twelve pieces of whatever the market gave us that morning. It is the honest version of the list, because nobody writes it down in advance and the kitchen has to stand behind what arrived.

Why all three ideas are on one menu

It is not an accident of fashion. Japanese emigration went to Peru and it went to Brazil, in large numbers and over generations, and it produced two distinct cuisines that both treat raw fish as a serious matter. Peru got Nikkei and tiradito. Brazil got its own sushi.

That is the reason this kitchen can put a ceviche and a maki roll on the same list without it being a gimmick. They are two branches of the same history, and the sushi side is a piece of writing in itself.

The tacos are the third branch, served as two: diced tuna with ponzu and goma wakame, or salmon with avocado, mango and masago. Raw fish in a shell is a Mexican borrowing on top of the other two, which tells you roughly how settled any of these boundaries are.

How to order it

Ceviche first, always. It is an opening dish by construction: cold, sharp, small, and it resets the palate rather than filling you up. Ordering it after something grilled is the one genuine mistake available here.

If there are two of you, the ceviche and the two sashimi plates cover the whole argument of this article in one sitting, which is a cheaper education than most and a better dinner than either half alone.

And if raw fish is somebody else's idea of dinner rather than yours, the rest of the South American kitchen runs to a charcoal grill and a moqueca, neither of which involves a lime.

One practical note

Ceviche is made to order and it does not improve while it waits. If you are ordering for a table and the plates are arriving in waves, ask for it to come when it is ready rather than held back with the rest. Fifteen minutes sitting in its own acid takes it from cured to tough.

That is also why it is the dish we would steer you away from at the very end of a long night. It is at its best early.
