Final answer:
To make a hot Cocomo with alternative milk, heat the alternative milk to about 90°C, let it cool slightly, then mix in cocoa, sweeteners, and any flavorings before serving warm.
Step-by-step explanation:
To prepare a hot Cocomo with alternative milk, one must first select an alternative milk option such as almond, soy, or oat milk. The process begins by using either whole or skimmed alternative milk or a high-quality powder of the chosen milk alternative. The milk is then heated to approximately 90°C, ensuring it is hot but not boiling as this can negatively affect the flavor and consistency. After heating, the milk is cooled slightly before the other ingredients constituting the Cocomo mixture are added, such as cocoa powder, sweeteners, and possibly additional flavorings. The drink is then mixed thoroughly until a smooth consistency is achieved and served warm.
