Take 250 grams of fresh turmeric. Wash it properly and cut it into thin pieces. Then, let it dry in the sun until it becomes completely dry.
In a pan, dry roast 2 tablespoons of fenugreek seeds, 2 teaspoons of yellow mustard seeds, 1 tablespoon of brown mustard seeds, and 2 tablespoons of fennel seeds. Stir and roast them for 2 to 3 minutes over medium heat until you smell a nice aroma. Turn off the heat.
Let the roasted spices cool down, and then grind them coarsely.
Take a pan and pour 250 ml of mustard oil. Heat the oil until it becomes very hot and starts to smoke slightly.
Turn off the heat and add 1 tablespoon of nigella seeds, 1 tablespoon of Kashmiri red chili powder, a pinch of Asafoetida, and the coarsely ground spice mix. Mix these ingredients well.
Once mixed, add all the dried turmeric pieces into this mixture. Stir everything together thoroughly over low heat for about 2 to 3 minutes.
Finally, add 2 tablespoons of salt and mix it well into the pickle.
Your Turmeric Pickle is now ready! Store it in an airtight container to keep it fresh for a longer time.
