How long does it take to cook red beans until they rot and turn into sand

Red beans usually need to be boiled for 30-60 minutes to become tender and sandy, and the specific time depends on factors such as soaking time, heat, and type of pot. Red beans have a hard texture and require a long time to soften when cooked directly. Soaking in cold water for 6-8 hours in advance can shorten the cooking time, and the red bean cell wall is more likely to rupture after sufficient water absorption. Using a pressure cooker can accelerate starch gelatinization through high-temperature steam, usually saving half of the time compared to ordinary cookware. Slow simmering over low heat helps to evenly heat the red beans, avoiding the outer layer from being burnt while the inner core remains hard. Old red beans may require longer cooking time due to fiber aging, while fresh red beans are easier to cook until they reach a sandy state. When using non soaked red beans or tools with fast thermal conductivity such as iron pots, there may be a situation where the skin cracks but the interior is not rotten. Some varieties, such as adzuki beans, have denser texture and require an appropriate extension of cooking time. Boiling red beans with acidic ingredients can delay the softening process. It is recommended to add seasonings such as sugar or vinegar after boiling until they are tender. Aged red beans that have been stored for over a year require longer cooking time to achieve the desired taste due to water loss.

It is recommended that when cooking red beans, the water should completely cover the ingredients, and hot water can be added in moderation to prevent the pot from drying out. Observe the cracking of the red bean skin and the thickening of the soup, then turn off the heat and simmer for 10 minutes, using the remaining heat to make it softer and more tender. When cooking with ingredients such as glutinous rice or lotus seeds, the heat and time should be adjusted according to the characteristics of different ingredients. People with weaker digestive function can extend the cooking time until the sand is completely dissolved, which is more conducive to nutrient absorption. Pay attention to controlling the amount of daily consumption. Red beans are rich in dietary fiber, and excessive consumption may cause gastrointestinal discomfort.
