Wash the pearl barley to remove any dirt and debris.
Drain the washing water and spread the barley grain on a mesh tray to sun dry the grain. *2
Roast the sun dried barley in a frying pan over low to medium heat until the grain browned. *3
Allow to cool completely then store in an airtight container.
Brewing Roasted Barley Tea
Bring 4 cups of water to boil in a kettle or pot over high heat.
Add 4 tbsp of roasted barley to the boiling water and simmer for 10-15 minutes over low heat.
Turn the heat off and serve through a strainer to serve hot. *4
Once it's cooled down, you can chill the brewed barley tea in a pitcher in the refrigerator to serve cold.
Notes
*1 I used 500g packet of pearl barley which is equivalent to 3 cups of barley.*2 It sun dried and left on a sunny spot all day. *3 Stir them often to avoid burning the barley. *4 Using a tea bag which you can get from Asian grocery shops or Daiso, makes it easier to serve and clean the pot.
