I feel your pain, and I haven't found a good answer for this yet myself after years of looking. As it is, the only nuts I've found to be safe thus-far are Fisher Nuts (baking nuts only)... which means trips to Small Wart and their baking department every once in a while. I've also had to grow to appreciate salting on my own or just going unsalted, and paying a near premium for the things. Heck, it's only been the past couple months that I even found a
safe peanut butter (unfortunately, it's sweetened - must be thankful for what I can get, however).
It's one of those things you wind up having to simply accept as a treat... it's like finding GF yellow mustard that doesn't cost an arm and a leg.
