Sansho pepper is not black pepper. It is made from the berries of the prickly ash. Sansho has a tangy, slightly lemon flavour and is often used in dishes like yakitori and eel to balance fatty flavours. How To Use A dash of sansho pepper will really liven up a dish. • Sprinkle on tempura or noodles. • Use as a condiment on shabu shabu or hotpot dishes. • Combine with salt and herbs to make a savoury crust for meat and fish dishes.
