This nutrient liquid can also burn when the temperature and time are high and long. It will create a layer of protein on top, and when you stir, it will change the texture of this drink.

It would be best to use a lid with a small hole to cover the cup or bowl when warming. This action will reduce the amount of water that evaporates.

If it is already hot or has deposited on the surface, your oven is hotter than usual. Otherwise, you can increase the time to 15-20 seconds for the next turn.
