Korean barley tea (boricha, 보리차) is made with roasted barley and water. In Japan, it’s known as mugicha.
You can buy pre-roasted barley grains from a Korean / Asian grocery store or you can roast barley yourself at home.
Alternatively, you can buy roasted barley tea bags, which makes all the work easier and quicker!
Boil the water in a kettle or pot until rapidly boiling. Add the roasted barley (in a tea strainer container if you have one) then boil further 5 mins on low to medium low heat. Remove the kettle from the heat and remove the roasted barley from the kettle.
Serve in a mug while it's hot or cool the tea down then transfer it into a jug. Refrigerate until needed. (If you didn’t use the tea strainer container, you will have to use the strainer to sieve the grains).
Enjoy your tea!!!
