Step 1Preheat oven to 200 °C/ 400 °F (conventional), or 180 °C/ 355 °F (fan assisted). Combine the spices, salt and pepper in a bowl and mix well.
Step 2Add the yoghurt, 2 tablespoons of oil and water. Stir to make a paste. If you use ghee or coconut oil it will solidify when combined with cold ingredients but that's ok.
