Denny's Server Training Practice Test

The correct total number of dishers used for preparing a vanilla shake is four. In food preparation, particularly at Denny's, using multiple dishers ensures that the right consistency and blend are achieved while allowing for efficiency during the serving process. Each disher serves a specific purpose: one might be used for the ice cream, another for any liquid ingredients, and additional dishers for other components such as whipped cream or sauces if included. This thorough approach allows servers to create a well-balanced and properly portioned shake that meets both quality standards and customer expectations.

Other options, representing a lesser number, would not accommodate the required variety of ingredients or the desired presentation. Essentially, using fewer dishers could lead to inconsistent blending or unequal portions, diminishing the overall quality of the shake prepared.
