Why do kidney beans need to be boiled?
Dried kidney beans need soaking and should be cooked carefully because they contain toxins on the outer skin when raw, which are rendered harmless by boiling; canned beans need just draining, rinsing and reheating. They’re great in mixed bean salads and stews such as chilli con carne.
Can you eat kidney beans straight from the can?
Tinned pulses have already been soaked and cooked, so you only need to heat them up or add them straight to salads if you’re using them cold. Dried pulses need to be soaked and cooked before they can be eaten. Dried kidney beans and soya beans contain toxins.
How do you soften kidney beans?
The most common way to soften dried beans is by soaking them in room-temperature water for several hours or overnight. Water initially enters the bean through the hilum, or scar, where the bean was attached to the stem in the pod.
