Heat a pan on medium-high heat. When hot, add mustard seeds. When they start to sputter, reduce the heat to minimum and add the asafoetida, curry leaves and chilli. Turn off the heat within seconds. Add carrots, salt, lemon juice, coriander leaves, coconut and date paste (optional). Mix well and serve.
Variation
You may replace the carrots with grated cabbage and tomatoes.
