Wagyu carpaccio and tataki, sliced and seared for a dinner party

What is the difference between Wagyu carpaccio and tataki?

Carpaccio is raw beef sliced paper-thin, laid flat on a cold plate and dressed at the last minute, usually with olive oil, lemon and salt. Tataki is Japanese: a block of beef seared hard on every face, chilled, then sliced so each piece has a cooked rim around a rare center. The sear is shallow. Japan's health ministry lists beef tataki with yukhoe, tartare and gyu-sashi as raw beef ^[6].

Tartare is the third option, chopped instead of sliced, and it has its own guide.

Japanese Wagyu fat turns liquid at 64–80ºF (what Wagyu tastes like), so a raw slice of it tastes waxy at fridge temperature. It softens after two or three minutes on the plate. It's best to send the plates out as soon as they're dressed and let them sit at the table.

Which Wagyu cut is best for carpaccio or tataki?

A lean, tight-grained muscle suits carpaccio, and a small, even block suits tataki. At A5, with BMS 8–12 (how grading works), a raw ribeye or striploin slice is mostly fat, so it makes a better garnish than a whole plate. Our current cow, Takemitsu-chan, is A4 with BMS 6, and the same cuts apply.

How do you slice Wagyu thin enough for carpaccio?

It's easiest half-frozen. Our beef ships frozen, so you're starting from a solid block anyway.

1. Thaw the pack in the fridge overnight, still sealed (unboxing and thawing).
2. Shape and firm it. Pat it dry, roll it tightly in plastic wrap into an even log, and freeze it for 30–45 minutes, until the outside is firm and the center still gives under your thumb.
3. Slice against the grain with a long, sharp slicer, one full pull per slice, about 1/16″ thick. A clean pull leaves smooth edges.
4. Press each slice between two sheets of plastic wrap with the flat of a cleaver or the base of a small pan, out to about 1 mm. Don't pound it, because Wagyu fat smears and tears.
5. Plate it cold. Lay the slices edge to edge in one layer on chilled plates, about 1½–2 oz each, cover and refrigerate for up to an hour.
6. Dress at the pass. Lemon left on raw beef turns the surface gray, so add the acid, oil and salt just before the plate goes out.

Some cooks sear the whole log for 10 seconds a face and chill it before slicing. That treats the surface, where USDA says contamination on an intact cut sits ^[2], at the cost of a thin gray edge on every slice.

How long do you sear Wagyu tataki?

About 20–30 seconds a face in a dry pan at 450–500ºF, far shorter than our steak timings.

1. Cut a block about 1″ square in cross-section: a misuji strip, or a filet cut into two bars.
2. Pat it dry and sear it straight from the fridge. A cold center stays rare.
3. Sear all six faces, ends included, 20–30 seconds each, until every surface has changed color. Stand the block on its edges with tongs. The whole sear takes 2–3 minutes.
4. Chill it fast. Seal it in a zip bag and drop it in ice water for 5 minutes, then refrigerate it for 30 minutes so it firms up for slicing.
5. Slice ⅛–¼″ against the grain and fan the slices down a long plate. Salt after slicing.
6. Dress it with ponzu, grated daikon, scallion and garlic chips, or with nikiri-shoyu and wasabi (Wagyu dipping sauces).

How much Wagyu do you need per person?

For a first course, plan on 1½–2 oz of carpaccio or 2–3 oz of tataki per guest. As a main, we suggest 4–8 oz per person. By our arithmetic from pack weights, before trim:

For a dinner of 12, one top round roast covers the carpaccio course with slices to spare.

Is it safe to eat Wagyu carpaccio or tataki?

Raw and rare beef carries risk, and neither dish meets USDA's guidance. USDA recommends cooking beef steaks and roasts to 145ºF with a 3-minute rest ^[1]. On an intact cut, any E. coli sits on the exterior, and USDA says cooking to that temperature kills it ^[2]. Grinding or tenderizing can carry surface bacteria inside ^[2].

The FDA's model Food Code for restaurants allows an undercooked whole-muscle steak if both faces reach a 145ºF surface temperature and every external surface shows a cooked color change, and only for diners outside highly susceptible groups ^[3]. Tataki follows that pattern. Carpaccio doesn't. Freezing doesn't close the gap. At 0ºF bacteria go dormant and become active again when the beef thaws ^[5]. Japan requires beef served raw, tataki included, to be heated 1 cm deep at 60ºC for at least 2 minutes in licensed facilities, and still advises children and older adults not to eat it ^[6].

When you plan the menu with the client:

• Consider the Food Code wording for the menu card. "Consuming raw or undercooked meats, poultry, seafood, shellfish, or eggs may increase your risk of foodborne illness" ^[4].
• Ask about the guests. Young children, older adults, anyone pregnant and anyone with a weakened immune system get a cooked course instead (raw and rare).
• Keep it cold. Hold the beef in the fridge until plating, and use a clean board and knife kept apart from other raw food.
