To start preparing this delicacy, beat the curd to make it smooth and combine it with water in a mixing bowl. Stir the beaten curd and water until you observe a medium consistency. Add turmeric powder and salt and stir again. Keep this mixture aside for further use.
Start heating ghee in a shallow frying pan on a medium flame. After the ghee heats up, add cumin seeds and mustard seeds. After you observe that the seeds are sputtering, add urad dal and let it cook until it turns red. Next, put dry red chili, green chili, asafoetida, curry leaves and snake gourd pieces into the mixture. Now let the entire amalgamation cook on a medium flame for about 8 to 10 minutes or until the snake gourd pieces start to tenderize.
After the snake gourd mixture is cooked, remove it from the heat and allow it to cool. Lastly, combine the mixture with the beaten curd and water (Step 1) and garnish with fresh coriander leaves. Serve fresh.
