In a kadai add the oil and fry the urad dal till it is golden brown. Add the red chillies, curry leaves, tamarind and mudakathan leaves and continue stirring till cooked. When cool, grind into a thick tuvaiyal with salt. Temper with mustard seeds, urad dal and asafoetida. Serve with hot rice. I found it tastes very good with tayir sadam. Serves 4.Â
