I saw the three meals a day in the rut and saw his sincere eyes when cooking black beans. I decided to give it a try.
Not much to say, take the beans for half an hour.
Add boiled beans. Then add water without passing the beans two centimeters, boil
Boil for half an hour after boiling water, small fire
Open the lid, add soy sauce, vinegar, sugar, stir from time to time
a very important step, collecting juice, shutting down the fire
Da da. Finished product. Sprinkling white sesame seeds is even better.
