Sansho: what every chef needs to know
Sansho — the Japanese variety of Sichuan pepper belonging to the rue family. Like Sichuan pepper, sansho contains hydroxy-alpha-sanshool and related alkylamides that cause the characteristic tingling and mild mouth-numbness. Sansho, however, has a pronounced citrus-fresh profile from a higher concentration of limonene and linalool, making the flavour more open, cleaner and less earthy than Sichuan pepper. In Japanese cuisine, sansho is inseparably associated with kabayaki (grilled eel), with tinned or grilled unagi, but also used with yakitori, gyoza dipping sauces and as a component of shichimi togarashi (seven-flavour blend). The young leaf (kinome) has a delicate, fresher aroma and is used as a garnish with sashimi and tofu in Japanese haute cuisine. Sansho is available as ground powder (sansho-ko) or as whole berries; powder is the standard form in European hospitality.

Sansho: preparation techniques
Exact temperatures and times for HACCP compliance. Core temperature is leading for poultry and pork.
Sprinkle sansho-ko (ground sansho) over kabayaki (grilled eel) just before serving; the citrus-tingling aroma dissipates quickly with heat. Use sparingly: 0.3-0.5 g per portion.
Add sansho powder to a shiro miso dressing or miso mayonnaise for a citrus tingle that adds complexity to miso dishes.
Sansho is one of the seven components of shichimi togarashi; mix with red chilli, white and black sesame, dried yuzu peel, nori and ginger for an authentic Japanese spice blend.

Frequently asked questions about Sansho
What is the difference between sansho and Sichuan pepper?
Sansho (Zanthoxylum piperitum) has a citrus-bright, fresher flavour with a high limonene content. Sichuan pepper (Zanthoxylum bungeanum) is deeper, earthier and with more heat. Both cause the tingling mouth-numbness but sansho is more refined and less sharp; it pairs better with fish and delicate proteins.
Why is sansho used with eel?
Kabayaki (grilled eel) is fatty and sweet in character from the caramelised tare sauce; the citrus tingle of sansho cuts through the fat, wakes the palate and accentuates the sweetness of the eel. It is one of the classic combinations in Japanese cuisine.
What is kinome?
Kinome are the young leaf shoots of the sansho shrub (Zanthoxylum piperitum), harvested in early spring. They have a delicate fresh-citrus aroma and are used as a garnish in Japanese haute cuisine with tofu, sashimi and soups.
At what temperature should you store Sansho?
Store Sansho at 10-15°C dry and dark, compliant with EU Regulation 852/2004 and Codex Alimentarius guidelines.
How do you prepare Sansho professionally?
The primary professional technique for Sansho is Grating of strooien over grilled paling at cold (after preparation) for immediately for serve. Always verify core temperature with a calibrated probe thermometer.
Does Sansho contain allergens?
Sansho is free from all 14 EU declarable allergens under EU Regulation 1169/2011 Annex II. Always verify with your supplier for processed variants.

Milk allergen and lactose intolerance
The EU-14 allergen "Milk (including lactose)" covers two distinct conditions, both of which require declaration: (1) cow's milk allergy, an immunological reaction to milk proteins (casein, whey), and (2) lactose intolerance, an enzymatic deficiency (lactase) preventing digestion of milk sugar. Both groups must be informed separately on the menu. Lactose-free is not the same as milk-protein-free: a guest with cow's milk allergy may still react to lactose-free products.
