What is Sansho Pepper
Sansho pepper is a spice used in powder and whole form. It has a delightful tingling and numbing sensation on your tongue.
The Japanese sprinkle it over unagi, yakitori, hot pot dishes, and noodles. It’s also one of the ingredients for the seven-spice blend shichimi togarashi. The Japanese cook down the fresh berries for tsukudani (佃煮), chirimen sansho (ちりめん山椒), and sansho miso.
Other parts of the plant, such as the flower, buds, young leaves, roots, and bark, are used in Japanese cuisine. The fresh leaves, called kinome (木の芽, literally “tree buds”), are used as decorative garnishes over grilled fish, bamboo shoots, rice, and soups. They are used to denote spring seasonality in food.
What Does It Taste Like
The strong citrus flavor has a pleasant, lasting tingle and a cooling sensation. It’ll stimulate your saliva glands and taste buds.
How To Use It
Sprinkle the condiment over unagi, poultry, fish, seafood, ramen noodles, and miso soup for the citrusy, floral fragrance and tingly sensation. You could also use it in Western dishes, such as steak sauce, salad dressing, or grilled vegetables.
