Heat a kadai/pan add cooking oil and roast bengal gram, split black gram and red chillies. When the split black gram and bengal gram change in color, then add ridge gourd skin and sesame seeds. Roast them together for 5 mins till the ridges become crisp. Now switch off the flame.

Now add tamarind, salt and jaggery to the same pan. Let it cool. Now powder all the roasted ingredients in a blender finely.

Ridge gourd skin chutney powder is ready. Relish it with idly, dosa or rice.

If the peeled ridges are one day older then it is better. Because the ridges would have become dry and moisture-less and chutney powder turns very good.

You can preserve it in airtight container for few days.
