Thanks for that U! I had a go yesterday. I cold smoked coarse sea salt for 4 hours. I then followed Wade's recipe, scaled down to 200g of cashews, using the sea salt in a momentary brine for the nuts, which were then mixed with blitzed smoked Maldon salt (off the shelf). I air fried them at 160c for 16 minutes, stirring half way. I think the time &/or temperature would stand a bit less. I then cold smoked them with oak dust for four hours - they are fab!
