Can you explain the brining process and how brining reduces cooking time and improves texture? GUY: The slow step in cooking dry beans is absorption of water into the beans to turn them soft, as well as gelatinize of the starch that must be cooked in order to be digestible.

Water can only be absorbed into the beans through a tiny opening called the micropyle, so the process is quite slow. Soaking beans in water for many hours reduces cooking time. However, in a pot of beans some beans may cook faster than others. This can lead to some beans bursting their skins, while other beans may not be cooked enough to be soft and creamy inside. Brining beans involves the same process as soaking in plain water except the brine contains a low concentration of salt sodium chloride.

During brining the sodium ions slowly exchange with calcium ions that are part of a very large molecule called pectin. Pectin strengthens the cell walls in the beans, and calcium strengthens pectin. So natural pectin can produce skins on the outside of dry beans that are difficult to soften and expand, and can eventually burst when the inside of the beans become over-cooked.

Exchanging sodium for calcium ions during brining weakens the pectin so the skins become more flexible and can expand without bursting as the interiors to cook to a soft creamy interior.

Extra: Try this activity using some different legumes legumes include beans, peas and lentils. Do some legumes absorb water faster than others? What does this tell you about how long they might need to be soaked before cooking them? Did you find that the black-eyed peas had a higher level in the cup with the hot water over time compared to in the cup with the ice cold water?

When dried beans are soaked in water, their volume increases as they absorb the water. Beans absorb hot water more quickly than cold water, which is why the black-eyed peas used in this activity should have swelled faster in the hot water than in the cold water.

For example, after only 10 minutes of soaking, you may have seen that the level of the black-eyed peas in the hot water cup was about half an inch higher than the level in the cold water cup, and that this difference remained consistent for the rest of the activity. This activity works well for dried black-eyed peas, split peas and lentils because they do not require extensive soaking before cooking; if you were to test other legumes that require more soaking, you would see that they absorb water much more slowly.
