As an aside, If you happen to have an airfryer, you can roast nuts in it very easily and quickly - for example I regularly do a handful of peanuts at 160c for 4 minutes without preheating.
I liquidise salt in my ninja blender which turns it to a fine powder. This sticks very evenly to the nuts. Also good for skinny chips/fries.
The toasted nuts taste far better than the ones that cost almost twice the price per kg. And they are absolutely amazing when still warm, but even cooled down I find them a lot nicer
I use them in Chinese cooking and the sauces & soy sauce can be salty enough, so I store some unsalted.
These are the ones,
Tesco Cashew Nuts 200G €2.39 (€11.95/kg)
they are in a resealable bag too, I cook the lot and put back in when cool.
