Nigiri vs sashimi

November 8, 2026 · Sushi Bar · MERO 18

Settle the nigiri vs sashimi question in one line: nigiri is a hand-pressed finger of vinegared rice with a slice of fish laid over it, and sashimi is the fish on its own, no rice at all. That's the whole difference — and it matters more than it sounds, because nigiri is the piece with nowhere to hide. No tempura, no cream cheese, no eel glaze, no crispy leek. Which is exactly why it's the smartest thing to order first at any sushi bar, including ours on Avenida Carlos Nader in downtown Cancún.

What nigiri actually is

The full name is nigirizushi, and nigiri means "to press with the hand." That's the entire technique, right there in the word. The chef takes a measure of seasoned rice, compresses it between the fingers into a small oblong, and drapes a slice of fish across the top. Traditionally a dab of wasabi goes between the two layers, working as both glue and counterweight. One piece, two ingredients, one bite.

It sounds easy and it isn't. A good nigiri holds together while you lift it and falls apart the moment it hits your tongue — firm on the outside, loose and airy inside. Too slack and it collapses on the way up; too tight and you're chewing a rice ball. Nobody gets there with better ingredients. They get there with hours behind the counter.

Nigiri, sashimi and maki, sorted out

This is the most common table-side confusion in any sushi restaurant, so here it is in three lines:

• Nigiri: rice with fish on top. It has rice, so it is sushi.
• Sashimi: sliced raw fish, no rice. Technically not sushi at all — "sushi" refers to the vinegared rice, not the fish.
• Maki: the roll. Rice and fillings wrapped in nori and cut into pieces. This is where sauces, crunch and combinations belong.

Our menu doesn't have a sashimi section as such, but it has its Peruvian cousin: tiraditos, thin slices of raw fish with cucumber, onion and avocado, dressed with tiger milk or ponzu — tuna $260 MXN, salmon $280. Maki lives in the rolls section, ten pieces each, from the Plantain & cheese at $165 to the Crab at $220. If rolls are your thing, we broke the whole category down in our guide to types of sushi rolls.

Why nigiri is the test

Order a breaded roll with tamarind sauce and you're mostly judging a sauce. Order a nigiri and you're judging three things at once, all of them naked.

The rice. It's roughly sixty percent of the piece and the part almost everyone overlooks. It should be close to body temperature — not fridge-cold — faintly sweet and sharp, with the grains still distinct. Over-vinegared rice buries the fish; unseasoned rice leaves it stranded.

The fish. With no batter and no cheese, the cut is right there in front of you: the sheen, the firmness, the absence of smell. You cannot dress up three-day-old tuna in a nigiri. That's why a bar running a live cold station — ceviches, aguachiles, tostadas — and working with the catch of the day has the advantage: the product turns over daily instead of waiting around.

The proportion. The fish should cover the rice and overhang slightly, neither falling short nor draping over like a blanket. That's a cutting decision made piece by piece, by eye.

How to eat nigiri without ruining it

There's no sushi police at this table, but a couple of these genuinely change how the piece tastes:

• One bite. Nigiri is sized for it. Cutting it in half collapses the piece and destroys the rice-to-fish ratio somebody just calculated.
• Flip it to dip it. Dunk it rice-side down and the rice drinks soy like a sponge — the piece turns salty and falls apart. Turn it over and touch only the tip of the fish to the sauce.
• Fish to the tongue. Rotate it on the way to your mouth so the fish lands first. The flavour arrives up front and the rice follows. It's the cheapest upgrade in sushi.
• Go easy on the soy. A touch. It's there to accompany, not to dye.
• Ginger goes between pieces, never on top. It resets your palate before the next fish.
• Fingers are fine. In Japan it's the normal way to eat nigiri, and honestly it's easier than chopsticks.

One last point on sequence: work from lean to rich. Shrimp, then tuna, then salmon, and leave eel for last — its sweet glaze lingers and flattens whatever follows it.

The four nigiri at MERO 18, with real prices

Our nigiri list is four lines long, and that's on purpose — we'd rather do a few pieces properly every day than carry a catalogue. They're sold individually, so you can build your own round without committing to a whole roll.

• Tuna nigiri — $60 MXN. The place to start. Lean and clean, and the piece that gives away freshness fastest.
• Shrimp nigiri — $60. The gentlest entry point if you're unsure about raw fish.
• Salmon nigiri — $70. Rich and round; the one almost every table orders twice.
• Eel nigiri — $70. The only sweet, smoky one in the set. Save it for the end.

One of each comes to $260 and gives you a full X-ray of the bar in a single order. You'll find them in the sushi bar section of the menu, alongside the ten-piece rolls, the pokes and the yakimeshi that arrived with our November menu.

Table split between raw-fish purists and roll people? Two nigiri each to open, one roll in the middle to close. It has never failed.

Where to eat nigiri in downtown Cancún

We're on Avenida Carlos Nader, in downtown Cancún, inside Mezcal Boutique Hotel and open to everyone — hotel guest or not. The place is a jungle hidden in downtown Cancún: palms, garden and a cenote-style pool, with a glass-walled, air-conditioned dining room for heavy middays and garden tables for sunset. We're open every day from 7:00 am to 11:00 pm, with breakfast from 7:00 to 12:30, so the bar runs from lunch straight through to dinner.

We hold 5.0 stars on TripAdvisor and 4.9 on Google. If you're still comparing, we mapped the whole scene in our guide to sushi in downtown Cancún.

Order one nigiri before you order anything else

It's the best advice we can give you at any sushi bar, here or anywhere: start with a single piece of tuna and decide from there. If the rice is warm and properly seasoned and the fish tastes of the sea rather than the fridge, the rest of the menu will take care of itself. If it doesn't, you found out before committing to a whole meal. Sixty pesos, well spent.

We're happy to sit the exam. Pick up the chopsticks, flip the piece over, and judge.
