1. Wash potatoes, peel them, and cut into small pieces.
2. Sprinkle with cumin grains, barbecue powder, top with barbecue sauce and olive oil, stir well, and marinate for one hour.
3. Spread tin foil on the baking tray, brush a layer of olive oil, and spread the potato pieces evenly. Put it in the oven, middle level, upper and lower fire, 230 degrees, about 30 minutes.
4. Take out the pan and serve.
Tips:Because the bagged barbecue powder and barbecue sauce sold in the supermarket contain salt, there is no need to add it. If the baby eats it, it can be replaced with light soy sauce, marinated in tomato sauce, and sesame seeds are added to make tomato flavor.
