I am indebted to Joe Evans for this dish, which marries the rich aromas of a curry with the speedy lightness of a stir-fry. The ghee is important to this dish for its flavor and high heating point. Serve with naan or pappadums.

Steps

1. Steam the potatoes until tender. Heat 2 tablespoons of the butter in a wide sauté pan over medium-high heat. Add the onion and sauté until well browned, about 12 minutes. Remove and set aside. Melt the remaining butter in the same pan over high heat. Add the cauliflower, season with salt, and sauté until it begins to color in places, about a few minutes. Return the onion to the pan and add the garlic, spices, and potatoes. Lower the heat and cook until everything is heated through, about 4 minutes. Add the greens, carrot, and ½ cup water. Cover and cook until the greens are wilted, about a minute. Season with lime juice and a few pinches of garam masala, then turn onto a platter and garnish with the sprigs of cilantro.
