Mostly we waste the skin of many vegetables,but we can use it many ways.One way of using it is we can make chutney like this with it.I learnt this from my sister-in-law.
Bitter gourd is not liked by most of us,even i too don't like it before but my hubby like it and whenever he use to come for vacation he will buy this.But i too started liking it specially this gravy.
This is my first time mixing a vegetable with dosa batter and make,must say even my kids eat well.It is very useful when children avoid eating such vegetables we can make like this and give.
