I guess so. At least you're not roasting roasted almonds. Besides the thought of another smoker's product in my Cookshack sends shivers up my spine.
I've seen recipes with much shorter smokes, maybe that's because they're already roasted. Mine turn out crispy, not burnt.
People seem to like them. Start with 2 hrs and take a sample. You can always smoke longer. I also figured the raw almonds would be cheaper than roasted.
I'm eating some as we speak, er write.
