A dried Persian lime (limu omani), pierced, optional but excellent
Method
Bring a large pot of salted water to a rolling boil. Blanch the spinach and mustard greens 45 seconds, then plunge them straight into ice water. Drain and squeeze out as much water as you can.
Blend the squeezed greens with the dill and green chilies into a coarse purée — leave some texture. Set aside.
Heat 1 tbsp of the ghee in a wide pan over medium-high and sear the paneer cubes on two sides until golden, about 3 minutes total. Move them to a bowl of warm salted water so they stay soft.
Add the remaining 2 tbsp ghee to the pan. Cook the onion 8 minutes until soft and lightly golden.
Add the ginger-garlic paste and fry 1 minute, then the LXV Silk Road Spice Blend and turmeric, toasting 30 seconds.
Add the pierced dried lime if using, along with 1/4 cup water, and simmer 3 minutes to draw out its sourness.
Stir in the green purée and the salt. Cook 8-10 minutes over medium heat, stirring — you want the raw edge cooked off without dulling the color.
Fold in the cream, then the drained paneer. Warm through 3 minutes only.
Remove the dried lime. Finish with lemon zest and juice and a scatter of fresh dill, and check the salt.
