Cool share. Thank you. I know when visiting Seoul, they tend to boil water in the very pot that they had cooked their meal in...then they sip that after a meal. Not always, but sometimes, I did not see it at restaurants but almost every home I visited, I experienced this - very interesting and possibly related to digestion? Not sure.
We use ginger. I just make a ginger tea with boiling water and a slice of fresh root ginger. Works each and every time. Love it. It tastes good too. I read that it even helps morning sickness. Worth a try, if the rice water does not work....or as another alternative.
