A Flavor Intensifier
Alternative to Hot Pepper Oil
Some cooks in Japan are beginning to experiment with using Japanese Pepper or Sansho as a seasoning for people who want to replace sodium, and also as a possible alternative to Hot Pepper Oil or Rayu, and as a flavor intensifier.
When Sansho is added to food, the food tastes salty, even if no salt is used. Sansho brings out the natural saltiness of the food itself. It intensifies the aroma as well as flavors of foods and can be helpful for people who need to reduce sodium intake.
