So you have to soak nuts overnight before you eat them?

i rehydrate my nuts in the shell but it takes more than 24 hours of soaking
in water.The kernel doesnt have the time to get the water. Nuts are
semiwaterproof for a reason they let the water come in but not too much (or
they will rot) so they can wait the right season to sprout.
i let mines in the rain ( that is abundant here in the winter) for days
before eating them ( they are stored dry and put them outside to have a
constant supply )
in a climate without rain i will store them in humid sand or peat moss
,because soaked in the water they get the chance of roting and the leaching
from the shell give a bad taste to the nut ( walnut)
i encourage anyone to eat rehydrated nuts they taste alive and are way more
easy to digest.
