Create the Masala Paste: In a blender, combine the poppy seeds or almonds, ginger, green chilies, 1 tbsp (15 ml) of fresh herbs, cinnamon, cloves, nutmeg, and water.
Blend until you have a completely smooth paste.
Set it aside for later.
Heat the Pan & Oil: Place a heavy-bottomed pan or wok over high heat.
Add your chosen fat—ghee, mustard oil, or vegetable oil. If using mustard oil, heat it until it just begins to smoke to mellow its pungent flavor.
Temper the Whole Spices: Once the oil is hot, add the kalonji and cumin seeds.
Fry for a few seconds until the cumin seeds darken slightly and become fragrant. Quickly stir in the asafetida powder.
Sauté the Potatoes: Immediately add the diced potatoes to the sizzling spices.
Stir-fry vigorously for 1 to 2 minutes, ensuring they get a nice, even coating.
Add Radish & Masala: Tumble in the shredded radish and pour in the masala paste you prepared earlier.
Stir everything together and cook for another 2 to 3 minutes, allowing the flavors to meld.
Cook Until Tender: Reduce the heat to medium-high.
Sprinkle in the turmeric and ground coriander powder.
Continue to cook, stirring frequently, until the potatoes are fork-tender.
Finish & Serve: Turn off the heat.
Fold in the salt, the remaining 2 tbsp (30 ml) of fresh herbs, and the fresh lime or lemon juice. Give it one final stir and serve immediately while hot.
