Decorative Cutting Across Cuisines: Shape, Open, or Even Out

What this article answers

What kinds of decorative cuts are there?

3 kinds: carve a shape to show, score cuts that open, or trim corners to make pieces even

What changes besides the look?

Scoring changes how heat and flavor get in. Even shapes make everything cook through together

How deep to score squid?

3/5 to 4/5 of the thickness. Never cut through: the rest holds the piece together

How do Japan, France, China, and Thailand differ?

In their signature techniques, Japan and Thailand carve shapes, China opens, and France evens out

A carrot cut into a plum blossom, squid scored like a pine cone, a potato turned into a little barrel. All three get called decorative cuts. Yet the plum blossom keeps its shape when simmered. The squid opens like a flower the moment it hits the heat. And every barrel in the pot finishes cooking at the same time.

They share a name, but the knife is doing something different in each.

This article sorts decorative cuts by kind and shows what each kind changes in the dish. It does not cover how to make each plum blossom or chrysanthemum.

Three kinds of decorative cut

Decorative cuts split into 3 kinds by what the knife does.

You carve a shape to show. You score cuts that heat or salt will open. Or you trim off corners to make pieces even.

Kind	What the knife does	Examples	What changes in the dish
Show a shape	Carve the outline of a flower, leaf, or bird	Twisted carrot plum blossom (nejiume), lotus-root flower, Thai fruit carving	Look and sense of season
Open	Score cuts that stop short of cutting through	Chinese hua dao scoring, kanoko squid, chrysanthemum turnip (kikka kabu)	Look, how heat gets in, how flavor gets in
Even out	Trim corners so pieces share one size and one number of faces	Tourné, roppo-muki, beveling	Even cooking, pieces that do not chip when plated

Most named cuts you will find, such as pine, bamboo, leaf, or rabbit, are shapes to show. The names are countless, but this article sorts them into 3 kinds by what the knife does.

How hidden cuts and ordinary cuts differ

Kakushi-bocho (隠し包丁, hidden cuts) also score the ingredient, just like cuts that open.

The difference is which side. Hidden cuts go on the side that faces down when plated, so they only handle how heat and flavor get in. Decorative cuts go on the visible side and show the opened shape as well.

Ordinary cuts aim only to make sizes even. How thin strips differ across cuisines is in julienne vs. sengiri vs. Chinese si.

Each cuisine favors a different kind

All 4 cuisines have decorative cuts. But line up their named signature techniques, and they cluster in different kinds.

Cuisine	Name for decorative cutting	Kind where signature techniques cluster	Signature techniques	Main ingredients
Japanese	Mukimono (剥き物), kazari-giri	Show a shape	Nejiume, lotus-root flower	Carrot, daikon radish, lotus root
Chinese	Hua dao (花刀)	Open	Wheat-ear pattern (mai sui), lychee pattern (li zhi)	Squid, pork kidney, white fish
French	Tourner	Even out	Tourné, château	Potato, carrot
Thai	Kae salak (แกะสลัก)	Show a shape	Watermelon flower, papaya bird	Watermelon, papaya, squash

Sources: China, a Sohu hua dao training text (2019); France, US Patent 7,278,346; Thailand, Thailand Foundation (2025); lotus-root flower, Sanjo City. The “kind” column sorts each source’s techniques into this article’s 3 kinds.

Japan and Thailand carve shapes, China opens

Mukimono is the Japanese technique of peeling and carving vegetables into flowers and leaves. Nejiume is carrot carved into a plum blossom, with a twist given to each petal.

The shapes carry meanings. Lotus root, full of holes, is said to give “a clear view ahead,” so it goes into osechi, the Japanese New Year food boxes.

Thai carving uses a single small carving knife to cut flowers and birds into watermelon and papaya. Ripe fruit is carved to be eaten, and hard unripe fruit is carved to last longer on display. In 2014, Thailand’s Department of Cultural Promotion registered it as intangible cultural heritage.

Chinese hua dao assumes the cuts will open into shape under heat. While raw, it looks like nothing more than a crosshatch.

France evens out the shape

Tourné means trimming root vegetables into barrels of one size and one number of faces (5 or 7). The middle is fat and both ends taper.

Château is a larger tourné cut from potato. At a Japanese culinary-school competition, one Western-cuisine task is to turn 6 matching château potatoes, each 5–5.5 cm (about 2 in) long.

French cooking has other decorative cuts besides tourné, such as scooping balls and carving grooves.

What makes scored cuts open

Only cuts that open change shape after you cut them. Two forces open them. Squid opens because heat makes it shrink. Turnip opens because salt makes it limp.

Squid opens because heat shrinks it

The outer skin of a squid’s body has 4 layers. In the innermost layer, collagen fibers run along the length of the body. When heated, this layer shrinks hard lengthwise, so the squid curls along its body.

If the cuts stop partway through the thickness, the uncut part shrinks while still holding the flesh together. On the outside of the curl, the 2 sides of each cut are then pulled apart. The edges are thought to bend back and open.

Japanese kanoko, nunome, and matsukasa squid are also scored on the body surface before grilling or simmering. The opened cuts add surface area, so more sauce or simmering liquid clings to it.

Turnip opens because salt softens it

For chrysanthemum turnip, you score a fine crosshatch into a small white turnip, then soak it in salt water.

Salt draws water out of the turnip and makes it supple. The strands between the cuts separate and open like chrysanthemum petals.

Soaking in salt water first also lets the sweet vinegar that follows reach deep into the cuts. Home recipes use 400 ml water with 10 ml (2 tsp) salt, about 3%, for 30 minutes in the fridge, then at least 1 hour in sweet vinegar.

Trimming corners evens out cooking and prevents chips

Cuts that even out do not open. Tourné and roppo-muki (peeling taro and similar roots into 6 faces) make every piece the same size and shape. Same shape, same cooking time, same result.

Beveling, called mentori in Japan, shaves a thin strip off each edge. It is often explained as a way to stop pieces from falling apart in the pot.

But chefs explain that its real purpose is to stop chopsticks from chipping the corners during plating. Falling apart can be prevented with the heat instead. Simmer at 80–90°C (176–194°F), with only a faint wisp of steam, and the pieces are said to hold together even without beveling.

Cut 3/5 to 4/5 deep, never through

With cuts that open, depth, blade angle, and crossing angle change the shape. For every ingredient, one condition holds: stop partway, never cut through.

Hua dao leaves 1/5 of the thickness

Chinese hua dao stops at 3/5 to 4/5 of the thickness and crosses cuts from 2 directions. The training text gives these values for each pattern.

Pattern	First cut	Second cut	Angle where the 2 cuts cross (°)	Best ingredients
Wheat-ear (mai sui)	Blade tilted to about 40°, to 3/5 of the thickness	Blade upright, to 4/5 of the thickness	70–80	Squid, pork kidney
Lychee (li zhi)	Blade upright, to 4/5 of the thickness	Blade upright, to 4/5 of the thickness	80	Squid, pork kidney
Chrysanthemum	Blade upright, to 4/5 of the thickness	Blade upright, to 4/5 of the thickness	90	White fish, chicken gizzards, tofu

Source: Sohu, “26 hua dao scoring techniques in Chinese cooking” (2019, reposted from a Chinese training text for cooks). Every pattern requires even spacing, depth, and blade angle throughout.

4/5 means leaving 1/5 of the thickness at the bottom. On a 5 mm (3/16 in) piece, that leaves 1 mm (under 1/16 in) at the bottom.

For fish and vegetables, set the stopping point first

Cut spacing depends on the size of the ingredient. Squirrel fish (song shu yu), a whole fish scored and fried into the shape of a squirrel, has lengthwise cuts 4–6 mm (about ¼ in) apart and diagonal cuts 2–3 mm (about ⅛ in) apart. You cut the flesh down to just above the skin, but never through the skin.

Vegetables use the same kind of stop. For chrysanthemum turnip, set the turnip between 2 disposable chopsticks. Score at 2–3 mm (about ⅛ in) intervals, stopping where the blade hits the chopsticks.

For jabara, an accordion-cut cucumber, the Japanese culinary-school competition gives full marks for evenly spaced cuts 2/3 of the way through its height.

When the depth or spacing is off

With cuts that open, how you score decides how they open. The training text lists the conditions. Break them, and this is likely what happens.

Hua dao cuts that are	What happens when heated
Too shallow	The edges do not bend back far enough, and no shape appears
Cut through the skin or the joined base	The flesh is no longer held together and falls into small pieces
Uneven in spacing or depth	Each spot opens differently, and you get neither a wheat ear nor a lychee

Source: an inference from breaking the conditions in Sohu, “26 hua dao scoring techniques in Chinese cooking” (2019): deep but not through, even throughout, skin left uncut.

Cooking has a signal too. Put hua dao squid into water at a hard boil, and lift it out once it has fully curled. The finished curl tells you when to stop.
