What's the Difference Between Sansho and Huajiao? Aroma, Numbing Tingle, Dish Pairings, and Substitutes Explained

The source of the tongue-numbing kick in mapo tofu and dan dan noodles is huajiao. It looks a lot like Japanese sanshō, so many people wonder, “Are sanshō and huajiao the same thing?” or “Can I substitute one for the other?” In fact, while they’re in the same family, their aroma, tingle, and role in cooking differ greatly.

This page organizes the difference between sanshō and huajiao in terms of aroma, tingle, and the dishes they’re used in. We cover what each is, the difference between green and red huajiao, the difference from the confusingly similar hana-zanshō, how to use each in mapo tofu and eel, and whether they can be substituted. The types of sanshō itself are covered inWhat is sansho? An explanation of the types.

What’s the Difference Between Sanshō and Huajiao? The Bottom Line

Sanshō and huajiao are both members of the Zanthoxylum genus in the citrus family, but they’re different spices made from different plants. Japanese sanshō has a refreshing aroma and refined tingle, while Chinese huajiao has a bright, strong aroma and a stronger tingle. Remember “sanshō for Japanese food, huajiao for tingling dishes like Sichuan cuisine” and you won’t get confused about which to use. Note that the sanshō compared here mainly refers to powdered sanshō used as a spice (fresh sanshō berries, kinome, and hana-zanshō are treated separately below).

What Sanshō Is (a Japanese Spice)

Sanshō is a deciduous tree in the citrus family native to Japan and is regarded as one of Japan’s oldest spices. Powdered sanshō is used on grilled eel (unagi kabayaki), fresh sanshō berries in tsukudani and chirimen sanshō, and the young leaves, kinome, for adding aroma to Japanese dishes. Characterized by a refreshing, cooling aroma and a refined tingle that lingers on the tongue, it’s a seasoning widely used in Japanese cuisine. WholeDried Japanese pepper (sansho)with the berries simply dried can be used for tsukudani, sanshō oil, and more.

What Huajiao Is (a Chinese Spice)

Huajiao is a spice made from the berries of the Chinese prickly ash (Zanthoxylum bungeanum), native to China. It’s in the same citrus family as Japanese sanshō but is a different type, with an entirely different intensity of tingle. The husk is dried and used—heated whole in oil to release its aroma, or ground into powder and sprinkled over dishes. It’s a seasoning essential to Sichuan cuisine, producing a strong aroma and tingle.

Chinese “málà” refers to a flavor that combines the numbing spiciness of huajiao (“má”) with the searing heat of chili peppers (“là”). The tingling kick of mapo tofu, hot pot, and dan dan noodles comes from this huajiao.

The Difference Between Sanshō and Huajiao | Aroma, Tingle, and Cuisine

Even within the same citrus family, sanshō and huajiao differ in aroma, tingle, and the dishes they’re used in. We’ve summarized the differences in a table.

Differences in Aroma and Flavor

Sanshō has a refreshing, cooling aroma reminiscent of citrus. Huajiao is brighter and stronger, with a distinctive aroma that comes through. Because the two point in different aromatic directions, using huajiao in Japanese food makes it taste Chinese, while using sanshō in Chinese food makes the flavor feel lacking.

Differences in Tingle and Spiciness

Both contain a compound that numbs the tongue, but huajiao’s tingle is far stronger than sanshō’s. Sanshō provides a moderate tingle as a condiment, while huajiao has a starring, powerful kick that makes an entire dish tingle. For dishes that call for a strong tingle, huajiao is the better fit.

Differences in the Dishes Used

Sanshō is used as a condiment or aromatic in Japanese food—grilled eel, tsukudani, miso, and clear soups. Huajiao is used in Chinese dishes that showcase a tingling kick, such as mapo tofu, dan dan noodles, and hot pot. Both are spices deeply tied to their food cultures.

Types of Huajiao and the Difference from Hana-Zanshō

Huajiao also has types, and it’s often confused with the similarly named “hana-zanshō.” Let’s sort this out.

Green Huajiao and Red Huajiao

Huajiao comes in green huajiao (qīng huājiāo), which uses young berries, and red huajiao (hóng huājiāo), which uses ripe berries. You use each to suit the dish.

• Green huajiao: More aroma-leaning. For finishing aromatics and dishes that make use of a cooling quality
• Red huajiao: More tingle-leaning. For dishes that showcase the tingle, such as mapo tofu and hot pot

Huajiao and Hana-Zanshō Are Different Things

Despite the similar names, huajiao and hana-zanshō are different things. Huajiao is a spice made from the berries of the Chinese prickly ash, while hana-zanshō refers to the flowers of Japanese sanshō. Hana-zanshō appears in spring and is an ingredient that adds a refined aroma to tsukudani and clear soups—an entirely different role from the tingle-forward huajiao.

How to Use Them and Whether They Can Be Substituted

Sanshō and huajiao each come into their own in their respective dishes. Let’s sort out how to use them and whether substitution is possible.

How to Use Each

Sanshō is used by sprinkling powdered sanshō on eel or soups, or making fresh sanshō berries into tsukudani. The prep for fresh sanshō berries is inPrepping Fresh Sanshō Berries, and how to use each by dish is inguide to using sansho. Huajiao is heated whole in oil to draw out its aroma and tingle, then added to mapo tofu or stir-fries. Sprinkling powdered huajiao at the finish is also standard. Both change the impression of a dish dramatically in small amounts.

When using them in recipes, think of the roles separately—sanshō as a “finishing condiment” and huajiao as a “starring aroma released into oil”—and you won’t go wrong. For example, even in the same spicy dish, using sanshō at the finish for a Japanese-style simmered or grilled dish, and huajiao during the heating stage for a Sichuan-style stir-fry or noodles, lets each shine. In málà recipes, huajiao and chili peppers are heated together in oil to draw out both the tingle and the heat.

Can Sanshō and Huajiao Be Substituted?

Substitution itself is possible, but because the aroma and tingle point in different directions, the result will be a different thing. Using sanshō in mapo tofu won’t produce as much tingle and aroma as huajiao, making an authentic flavor hard to achieve. Conversely, using huajiao on eel takes it away from a Japanese flavor. So the basic recommendation is to use each to suit the dish. If you truly have neither on hand, try a small amount, understanding that the aroma will change.

Frequently asked questions

Summary: Sanshō for Japanese Food, Huajiao for the Tingle of Chinese Cuisine

Sanshō and huajiao are members of the same citrus family, yet different spices. Japanese sanshō, with its refreshing aroma and refined tingle, is for Japanese food such as eel and tsukudani. Chinese huajiao, with its strong aroma and tingle, suits the tingling dishes of Chinese cuisine, like mapo tofu and dan dan noodles. Huajiao comes in green and red, and the similarly named hana-zanshō is the flower of Japanese sanshō—a different thing.

Because the aroma and tingle point in different directions, the sure approach is to use each to suit the dish rather than substituting. Remember sanshō for Japanese food and huajiao for the tingle of Chinese cuisine, and you won’t be at a loss. The types of sanshō and how to use it are inWhat is sansho?
