Notes
If you wish, you can add a tempering to the chutney. For the tempering, you need to heat 1 tbsp oil. Add ½ tsp udad dal, ½ tsp mustard seeds and few curry leaves. When the seeds start crackling, pour the tempering into the chutney.
Brahmi plant can be easily grown in pots. It grows well in partial sunlight/shade. The plant can be easily procured from your local plant nursery. A brahmi plant growing in a kitchen garden would mean regular supply of brahmi leaves whenever one needs it. However, if you are not up for growing brahmi plant at home, the leaves are now available online too. So, do try to procure the leaves and make this healthy chutney.
