Choosing the chilies depends upon your taste. If you like hot and spicy pickles, then go for the spicy chilies, but if you like the pickle to be less spicy, go for the milder green chilies.Some people’s skin is sensitive and the chilies can cause burn on the palms. If you are one of those, then try to wear gloves while handling the chilies. If you don’t have gloves, then wash the hands immediately after handling them and if the burning sensation is still not gone, then dip the pams in cold milk for 5 minutes.Do not overcook the pickle. The chilies must be slightly crunchy.You can replace dry mango powder with lime juice but the shelf life will reduce a little.
