What is the purpose of blending on #3 for the strawberry smoothie?

The purpose of blending on #3 for the strawberry smoothie is primarily to mix ingredients thoroughly. When smoothies are made, especially those that contain fruits, yogurt, or other ingredients, it is essential to achieve a consistent texture and flavor throughout the drink. Blending at a specific speed helps to ensure that the strawberries are well integrated with any other components, such as ice and milk, effectively creating a uniform mixture. This thorough blending not only improves the overall taste but also affects the mouthfeel, making the smoothie enjoyable to drink.

In this context, while options like creating a thicker consistency or making it frothier might be aspects of the blending process, the primary goal of using a specified blending option is to ensure that all ingredients are well combined. Cooling down the smoothie is not related to the blending speed or technique but rather to how ingredients are prepared or if ice is included in the recipe.
