Revive a Sunnah: Leaving Hot Food out to Cool

When ‘Asma bint Abu Bakr used to cook a broth she would cover it with something until the hot bubbling steam had left, then she said: verily I heard the Messenger of Allah say: “Indeed it is greater Baraka (blessings). i.e. the food from which is not bubbling and steaming.” (Authenticated by Al-Albani)
