Sugar-Free Red Bean Paste

Rinse the red beans thoroughly.

Soak the red beans in cold water for at least 5 hours.

Put the soaked red beans in a pot, add plenty of water, and bring to a boil.

Once it starts boiling, discard the first batch of water and add fresh water.

Boil until the beans become very soft.

Drain the cooked beans and mash them finely.

Put the mashed beans in a pan and cook over low heat, stirring to evaporate excess moisture.

Season with salt and let it cool completely.
