In a pan heat the oil and splutter the mustard seeds, then the jeera.
Add the urid dal and let the dal turn reddish then add the sesame seeds.
The sesame seeds splutter so be careful.
Next, add the green chillies and stir fry. Again chillies splutter so take care.
Toss the garlic cloves then add the onions. Stir fry add a little salt, say a pinch. This hastens the process of browning.
Once the onions are well done add the ridge gourd, tamarind and stir fry till the gourd wilts.
Add the coconut and stir fry for a minute or 2 then add the coriander stalks, salt. Remember you have added some earlier so go easy on the salt. You can always add some later.
Switch off the gas and let the ingredients cool down totally.
