How long does it take?
Probably 24 hours. I have also strung them and air dried them if they are not too thick. Works especially well with cayennes. I don’t even split them just hang them using super long twist tie stuff. When dry I pierce a few holes in each one with a toothpick and put in a jar of Bertoli extra light olive oil. After a few days out on the counter the oil will start turning pink. I would just use a little bit of the oil in the pan.
