The ratio of liquid to rice and the cooking time are the main factors that determine the texture of the pudding. Generally, a ratio of 4-5 cups of liquid for 1 cup of rice is a good start. Note this is a small batch using only 1/2 cup of rice. If your pudding is too dry, it might need more liquid or less cooking time. If it's too thin or soupy, it might need more time to cook, or you may have used too much liquid.
