I soaked some beans the other day. Kidny beads and some others. Seemingly I've ruined them as beans shouldn't be soaked for longer than 12 hours.

You live and learn!

Also kidney beans need to be treated carefully

"You must prepare the beans properly:

If you buy dried kidney beans, it's important to cook them properly. This is because kidney beans contain a natural toxin (called lectin) that can cause stomach aches and vomiting. However, it's easy to destroy the toxin if you prepare the beans properly.

Follow these three steps to destroy the toxins:

1. soak the dried beans for at least 12 hours
2. drain and rinse the beans then cover them with fresh water
3. boil them vigorously for at least 10 minutes

Then you need to simmer the beans for approximately 45 to 60 minutes to make them tender.

If you buy tinned kidney beans, they have already been through this process so you can use them straight away.
