Add 1 cup of short grain white rice to the mixing bowl with the soaking multi-grain mix.
Then add a handful of the soaked beans into the bowl as well.
Finally, add 1.5 Tablespoons of the black rice into the bowl. Give it a thorough mix with your hand.
Then, pour the wet rice mixture into a strainer. Discard the remaining water.
Then, take out a thick-bottomed pot. Place the mixed rice in. Pour in 2 cups of fresh cold water. Put a lid on. Then place the pot on a medium-high heat and bring it to a boil.
Once you hear it boiling, lift the lid and quickly mix the rice with a spoon.
Then, place the lid back on and reduce the heat to a low (simmer). Let it simmer for 5 minutes.
Then take it off the stovetop. And let it sit by itself for 10 minutes. This is an important step - the rice will steam in the residual heat.
After 10 minutes, the rice should be ready. Eat alongside a bowl of banchan!
Note: If rice seems undercooked, close the lid and let it sit for longer in the pot. However, if the pot has lot most of its heat, place it back on the stove-top and cook for longer on a low heat.
