Wash and peel the carrots. Then cut them into slices of 7 cm per piece, however note that the pieces should not be too thin.
Take a large bowl, put in the carrot pieces along with all the ingredients together and mix well for 1-2 minutes.
Next take a clean jar and put in the achar mixture, cover it with a tight lid.
It is best to leave this jar in the sun for 6-7 days so that it forms a good gajar ka achar.
Remember to give the jar a good shake atleast once a day so that all the carrot pieces get in touch with the heat.
Serve this delicious achar with your aloo ka parantha.
