Final answer:
Blenders are commonly used to make frosts, but alternative milks can be used as well depending on preference and dietary restrictions.
Step-by-step explanation:
The statement 'Frosts are better when made with alternative milk rather than in a blender' is false.
Blenders are commonly used to make frosts as they are able to efficiently blend and mix all the ingredients together. Alternative milks, such as almond milk or soy milk, can also be used in frosts if someone prefers a non-dairy option.
However, whether a frost is better made in a blender or with alternative milk depends on personal preference, dietary restrictions, and the specific recipe being used.
