Boil the beans
60 minDrain and rinse the soaked beans, then put them in a pot with 1.5 liters of fresh water. For the first 10 minutes, boil rapidly with the lid off; this vigorous boil breaks down the natural toxin in red kidney beans. Then cook over medium heat for 50 minutes, until the beans crush easily between your fingers. Reserve and strain 100 ml of the cooking water.
