I went with the rotisserie and basket but you can do it in a cast iron pan over the coals just as well.
Aim for about 400f/203c direct
Score the nuts with a pairing knife putting an X on the flat side. This will prevent them from exploding
Cook for 12 min. Serve immediately with some smoked sea salt. Enjoy
