Tips

  • If you don’t have mentsuyu, soy sauce works perfectly!
  • It tastes better well-chilled, so instead of eating it right away, refrigerate for 30 minutes to 1 hour for the best flavor.
  • You can use honey ume or shiso ume. Since this recipe includes sugar, honey ume will make it sweeter.
  • Feel free to omit the sugar if you prefer!
