The four words in this title get used as if they're synonyms. They're not. Each one names a specific way of treating raw or lightly-treated protein, and each one came out of a different cuisine answering a different question. Choosing between them at home is partly a flavour decision and partly an honesty decision — the more you know about the differences, the more you can name what you're actually serving.
This page sits next to our existing tartare vs. carpaccio comparison and goes wider: it adds crudo and ceviche, and it ends with a decision matrix you can use when you're standing at the counter with a piece of fish.
Quick definitions
- Tartare — finely diced raw meat or fish, seasoned and served immediately. Originally a French preparation associated with beef; now applied widely.
- Carpaccio — very thin slices of raw beef (originally) or fish, dressed lightly with oil, lemon, salt, and sometimes Parmigiano. Italian; a 20th-century dish despite the name.
- Crudo — literally "raw" in Italian and Spanish; a category, not a recipe, used for raw fish dressed simply with oil, citrus, and salt. The cut varies (slices, batons, occasionally cubes), as does the dressing.
- Ceviche — raw fish or seafood marinated in citrus juice for long enough that the surface clearly denatures. Latin American in origin; many regional sub-traditions, especially Peruvian and Mexican.
How they differ at a technical level
| Tartare | Carpaccio | Crudo | Ceviche | |
|---|---|---|---|---|
| Cut | Hand-diced cubes (1–5 mm typically). | Very thin slices, usually flattened against the plate. | Thin slices or small batons; less standardised. | Cubes or slices; size depends on regional tradition. |
| Treatment time | None to minutes. | None — dressing applied immediately before service. | None — dressing applied immediately before service. | Minutes to a couple of hours in citrus. |
| Visible change | Slight darkening from oxidation, no opacity change. | Stays glossy and translucent. | Stays glossy and translucent. | Visibly opaque on the surface, sometimes throughout if cured long. |
| Typical seasoning | Mustard, capers, shallot, Worcestershire, herbs, yolk on top. | Olive oil, lemon, salt, optional cheese or rocket. | Oil, citrus, salt; sometimes a single herb or chilli. | Citrus juice (often lime), onion, chilli, salt; regional add-ons (corn, sweet potato, leche de tigre, etc.). |
| Origin | French; modern form 19th–20th century. | Italian; mid-20th century (Venice). | Italian/Spanish; broad descriptor. | Andean / Pacific coast Latin America; centuries old, with regional schools. |
The most useful axis: how much does the technique change the ingredient?
If you order the four by how much they alter the protein, you get this:
- Crudo — least altered. The dressing arrives at the moment of service and barely interacts with the flesh.
- Carpaccio — almost as little; thin slicing is a textural decision, not a chemical one.
- Tartare — altered by dicing (lots more surface area) and by mixing in seasoning. Still raw inside.
- Ceviche — significantly altered on the surface; depending on time, possibly throughout. The closest of the four to "cooked", though not actually cooked.
This axis is usually more practical than the country-of-origin axis when you're deciding what to make. It tells you how forgiving the dish is, how much it cares about the supplier, and how long it can sit on the bench.
Worked example: the same tuna, four ways
Imagine a small block of high-quality tuna, treated in compliance with the freezing rules where you live. Four routes:
- As tartare. Dice into 4 mm cubes. Dress with lime juice, soy, sesame oil, finely-chopped chive. Serve on a chilled plate within ten minutes.
- As carpaccio. Freeze briefly to firm, slice as thinly as you can with a long knife, lay flat on a chilled plate. Drizzle with good olive oil, sea salt, a few drops of lemon, optional Parmigiano shavings.
- As crudo. Cut into long batons or thin slices. Plate cleanly. Dress with oil, lemon zest, sea salt. Maybe a single thin slice of bird's-eye chilli. Nothing more.
- As ceviche. Cut into 1 cm cubes. Toss with lime juice, finely-sliced red onion, salt, chilli. Hold in the fridge for ten to twenty minutes — the surface goes opaque, the centre stays raw. Serve with a corn or sweet-potato side.
You ate the same fish four times. You did not eat the same dish.
Decision criteria
When you're trying to choose, run through these in order:
1. What's the supplier and the source?
Crudo and carpaccio are the most exposed to ingredient quality — there is nowhere to hide. If you have a fish you can confidently source raw, those two flatter it. Tartare and ceviche tolerate slightly more flavour intervention, which means a slightly more flexible supplier. None of them tolerates an unsafe supplier — see the selecting safe seafood page.
2. What's the texture you want?
Soft and glossy: crudo. Soft and silky: carpaccio. Bouncy and even: tartare. Firmer with a yielding centre: ceviche.
3. How much technique are you willing to deploy?
Carpaccio is the most technically demanding because the slices have to be uniformly thin. Crudo and tartare are about evenness more than thinness. Ceviche has the simplest knife work; the timing is the discipline.
4. How long until guests sit down?
Tartare and crudo collapse if they sit dressed. Carpaccio holds for a few minutes — the flat surface is forgiving. Ceviche is the only one that benefits from sitting (within reason) — the surface needs the citrus contact.
5. Who's eating?
None of these are equivalent to a cooked dish for food-safety purposes. If anyone at the table is in a higher-risk group (pregnant, immunocompromised, very young, very old), the right answer is a cooked alternative. See our disclaimer and the food safety guide.
Common mistakes when crossing categories
- Calling a chunk-cut, citrus-dressed dish "crudo". If you've cubed it, you've made tartare or ceviche depending on time. Crudo is mostly a slicing tradition.
- Calling a long-marinated tartare "ceviche". If the centre of the cube is opaque, you've crossed into ceviche territory. Either embrace it or shorten the marinade.
- Adding tartare-style seasoning to carpaccio. Mustard and Worcestershire bury thin slices.
- Heavy citrus on a beef carpaccio. The thinness already amplifies acid; a normal squeeze of lemon can cure the surface visibly.
Where to start, depending on what you have
- Excellent beef tenderloin. Tartare. The seasoning tradition matches the cut perfectly. Recipe: classic beef tartare.
- Beef sirloin or eye round, very fresh. Carpaccio. The thin slice forgives a slightly less buttery cut.
- Pristine salmon or tuna. Crudo or a brief-cured tartare such as our salmon citrus tartare.
- Firm white fish (sea bass, halibut), citrus, chilli. Ceviche. Marinate ten to fifteen minutes; serve cold.
