main issue we face in making any pudding recipes is lumps formation. You have to mix the corn flour and milk without lumps.
also have to take care when you add the corn flour mixture to the pan. If you see any lumps, break it immediately. Also, you have to switch off the stove in right consistency. Do not overheat it. You will get lumps surely.
