We use an older Excalibur dehydrator, a fine machine. For nuts, I use a whirly-pop, or stove top crank popper. Toasts them very nicely. Almonds, pecans, hickory, walnuts etc.. I have not had raw peanuts to try. I put a tad bit of oil in the bottom, then either a sweet or savory seasoning. For sweet we use brown sugar. Savory, I usually use a ranch seasoning or seasoned salt, both from Lawry’s. Medium heat and constant cranking. I have 2 stovetop poppers, neither for popcorn The other I roast coffee.
