Salt crystals Take a clean dry jar and put one layer of mangoes and one layer on salt crystals.
Repeat this till all the mangoes are packed in, covered with salt. Put the lid back, tie a cloth round the neck and keep aside for 1 week. Meanwhile, soak the chilli and mustard in saturated salt water and grind it to a fine paste. Take out the mangoes when it is fully shrunk. Strain the juice out, boil till the salt starts crystallizing.
