I usually soak and dry walnuts. It tastes much better. Unfortunately, last time, I found that it has developed mold. I soaked them for a night, I dried them for several hours at a very low temperature, and when they were crunchy and seemed dry, I stored them in a crystal container in a cupboard.
Put some newspaper in the container and it will absorb the moisture first.
Storage of nuts, I generally make a couple layers. I add clean folded paper towel between each layer as I place them in a jar. After the first night, I open the jar, pour them out, check the paper towel for dampness, texture and smell. If all is well, paper towel is trashed and nuts go back in the jar. If I feel or notice any dampness, I spread them out on a clean surface, cover with clean paper towel for a few hours. Return nuts to jar minus paper towel.
