Either (a) long-soak the dried kidney beans overnight covered with water, OR (b) quick-soak by covering them with water in a saucepan, bring to a boil, boil 2 minutes and let stand for an hour. However the beans were soaked, drain and discard the soaking water. Put in a pot, cover with fresh water, boil 30 minutes.
The amount of this toxin in beans is usually measured in terms of hemagglutinating units, or hau. In their raw form, red kidney beans can contain 20,000 to 70,000 hau. This number drops down to 200 to 400 hau with fully cooked red beans. White kidney beans start off with about 1/3rd less hemagglutinin than red ones.
