Wash the chickpeas and keep it aside to dry
Wash and clean the mangoes, grate them(without peeling)
Mix the chickpeas,grated mango and Salt.
Cover it and keep it aside for 6-8 hours in sun.
This will help release water from the grated mangoes , that will be absorbed by the chickpeas.
Mix all spices along with fennel, fenugreek seeds,spices with oil and,vinegar
Take a dry and clean glass bottle and transfer the mixture to the jar.
Push the pickle below the oil using a spoon,the oil will rise above after a few days as well.
Keep it in an airtight jar in sunlight. Allow it to rest in the sunlight for at least 2-3 weeks, in between mix the ingredients using a clean and dry spoon every 2-3 days. Depending on the summer heat, this might take more time. I leave this out in the balcony for a month or more if its not ready.
Store this in a cool dry place.
