In a medium skillet or tawa, add the vegetable oil and turn the heat to medium. Add all of the spices and cook, stirring continuously, until fragrant, 2–3 minutes. Transfer to a bowl and set aside cool to room temperature, about 15 minutes
Transfer the spices to an electric spice grinder or coffee grinder and process to a fine powder. Use immediately or transfer to a glass jar with a tight-fitting lid and store for up to three months.
