The Trick To Preventing Beans From Opening While You Cook Them
If your beans break open while cooking and turn into a mess, you can ensure that they maintain their shape by utilizing gentle simmering and infrequent stirring.
Maintain a low, steady heat that barely causes movement in the pot. Start by bringing the pot to a gentle boil and reduce the heat to low once it bubbles to let the beans simmer.
Resist the urge to stir the beans too frequently, which causes the beans to open. Instead, stir very gently and only occasionally to redistribute the beans.
