What type of shake requires 6 oz of milk?

The choice of a Vanilla Shake requiring 6 oz of milk is accurate because traditionally, a classic vanilla milkshake is made with a specific ratio of milk, ice cream, and flavoring or vanilla extract. The 6 oz of milk is essential for achieving the desired consistency and creaminess in the shake, enabling it to blend well with the ice cream and other ingredients.

Vanilla shakes typically rely on a balanced mixture of milk and ice cream to create a classic flavor profile, which is why the measurement of milk is particularly highlighted in this context. Other shakes might vary in their recipes or ingredient proportions, which could account for different milk requirements.
