Learnt this one too from my Mum-in-Law.
And yep, once you read the recipe don't pop your eyes with surprise at the typical 'secret' gujju ingredient.
Trust me, it adds a whole different flavour to these sabjis.
This is my husbands favourite sabji with freshly baked rotlis and ghee.
Do give it a try this way.
Bon Appétit
