A tip to making delicious bean paste is adding the sugar in 3 steps after the beans become soft completely. If you add the sugar while the beans are still firm, the beans will stay firm even if you cook them for a longer time.
This white bean paste contains bean skins, allowing you to taste the whole beans.
When you freeze the bean paste, divide it into smaller pieces and store them in the freezer.
You can use a pressure cooker to reduce the cooking time of beans. Follow the instructions of your pressure cooker.
