Whether you chose the lazy overnight soak or the hot-power-nap, the end result is the same. Pour the beans into your colander again.
Discard the soaking water. It’s full of starches and oligosaccharides (the fancy name for “toot fuel”). You want fresh, clean water for cooking.
Give them another quick rinse under the tap. A final, gentle see-ya-later to the old water. Now your beans are pristine and ready.
