Whenever my children gets an itchy throat, I make this right away. Dilute this recipe with hot water and make a drink to relieve sore throats (I came up with an extra use for this recipe!)
My grandma used to make this when my mom was little and when she had a sore throat.
There are no hints.Even daikon radish by itself works for relieving a sore throat.
Enjoy Japanese food around the world.
