2 tablespoons canola oil (ghee) or 2 tablespoons clarified butter (ghee)

In a heavy pot, heat the ghee or oil until shimmering. Add onion and cook slowly, stirring often, until golden, about 20 minutes. Add ginger, garlic, tomato paste, garam masala and chili powder.

Remove from heat and stir in yogurt. Serve over cooked jasmine or basmati rice.
