Roughly chop the spinach leaves if large and set aside—not necessary if you're using pre-washed baby spinach. (If using frozen spinach, remove from package and set in a colander to thaw in the sink or set over a plate. Squeeze out as much liquid as possible and rough chop if leaves are large.)
Heat ghee or oil in a large pot over medium-high heat. Add the paneer and brown on all sides, turning carefully with a wooden spatula or tongs, so you don't leave the crust stuck to the bottom of the pot. Transfer to a paper towel lined plate and set aside.
Add onion to pot and cook, stirring with a wooden spatula or spoon, until it begins to soften, about 5 minutes. Add the garlic-salt mash, spices, ginger, and cook for a couple minutes.
Turn up the heat to high and add the spinach; cook, turning from bottom to top, to wilt, about 5 minutes. Add the buttermilk and cream and simmer until thickened, another 5 minutes or so. Add the nutmeg and black pepper, then stir in the paneer. Enjoy!
