A healthy ayurvedic buttermilk flavoured with curry leaf, ginger and green chilli. Diluted curd or buttermilk is a very excellent home fertilizer for the curry leaf plant. You need to allow the soil to dry completely before watering the plant. Buttermilk is very high in Nitrogen, which the curry leaf plant needs. Buttermilk makes the soil acidic, which the curry leaf plant loves very much. A refreshing Indian drink made with a difference.
