For this quick Indian pickle recipe, begin by finely slicing the onions and chopping the green chillies.
In a mixing bowl, combine the onions and chillies.
Then add all the spices—turmeric, red chilli powder, chaat masala, amchur powder, and salt. Toss everything together until the onions are evenly coated.
Next, heat mustard oil in a small pan. Add asafoetida, fennel seeds, and nigella seeds.
Once the spices begin to crackle and release their aroma, remove the pan from heat and pour this tempering over the onion mixture. Mix thoroughly.
Finish by adding lemon juice and stir well so that each slice of onion is coated with the spicy, tangy flavors.
