This module is the second in a five-part series. It can be used to support learners in LBS and/or pre-apprenticeship who are interested in food service/cooking. In this module, participants will learn how to scale recipes with a calculator, and then they will learn how to scale using Microsoft Excel. In addition, this module will teach students about yield factors, how to conduct a yield test on a product, and how to calculate a yield factor. Also, an activity is included where the student must attach a recipe (scaled in Excel) to an email, and send it to their “chef” (instructor). A simple kitchen scale is required for the final activity (the “Yield Test”). Familiarity with Excel at an introductory level is recommended. Answer keys for practice activities are provided in the document.
