Dhonepatar Patar Chutney / Coriander Chutney
This Coriander Chutney has a different preparation... Normally the ingredients are ground raw and the chutney is ready. I remember one of the cook at my Aunt's place use to make this in Kolkatta. She use to called it Dhonepatar Bhorta and it was had with hot rice. This chutney is cooked with mustard oil and has a sweetly, tangy, spicy taste and can be preserved for 3 to 4 months. This chutney can be used to have on bread or can be used for cooking with fish or chicken.
