Black Bean Water
1.
I uploaded barley water before, and occasionally saw black bean water on the Internet, so I thought it was good to try. Don't fry too much at a time, do not add oil, repeatedly stir fry in the pot, slightly cracked, turn off the heat and cover the pot to simmer. The pot is cold and put in the lunch box. It is best to seal the pot.

Just add hot water to brew

This is the second cup, it's really super simple, and the taste is okay.
