Getting seasoning of any sort to stick to nuts is best done using a method that involves oil such as oven-roasting or cooking over stovetop.  When simply adding salt to nuts, soaking and steaming methods work great. However, if you are trying to get coarser seasonings such as rosemary and other herbs to stick to your nuts, you’ll need to heat your nuts using oil over the stove, or using oil and an oven to get your seasoning to stick.
