My Grandmother's Simmered 'Kuromame' Black Soybeans

• 400 ml Kuromame
• 1200 ml Water
• 200 ml Sugar
• 1 tsp Salt
• 1 tsp Baking soda

1. Gently rinse the kuromame.
2. Put the ingredients in a large, deep pot, bring to a boil, then add the baking soda.
3. After adding the baking soda, turn off the heat, add the beans, then let sit for 8 hours (overnight).
4. Turn on the heat, simmer for 1 to 2 hours on low heat, skimming off the scum from time to time (check the softness of the beans and adjust the cooking time accordingly).
5. The pot will boil over if the lid is sealed, so loosely cover the lid.
