The formula:
- take equal amount of barley, huai shin & fox nut
- get the shop to grind it until it's powder-like (see picture)
To eat, you can either:
- put 2 spoonful and mixed it with lukewarm water, then bottom up and it's tasteless; or
- put 2 spoonful, mixed it with water and bring it to boil, cool it before eating the cereal-like mixture and it's still tasteless.
Hubby is fond of the latter and he's happy with the result so far and I'm happy that he's happy.
