Putting the child on the bed to let her sleep, and seeing that it's still early, the tea eggs made yesterday have almost been soaked enough.
Externally made items placed in the space can stay fresh, while food made within the space not only stays fresh but can also undergo quality changes over time; however, this process is very slow. So she wouldn't wait for the food to go bad before eating it, as the quality change in the space is based on an external 1, space 2 ratio.
In other words, 24 hours outside equals 50 hours in the space. Food made in the space naturally comes with Spiritual Energy, and in a space rich with Spiritual Energy, microorganisms are isolated, making mold and spoilage impossible. At most, it loses its initial freshness, but this change might not even be visible to the naked eye.
Therefore, the tea eggs made last night should indeed be flavorful today, rather than preserving in the same state they were made in.
