Which of the following is included in the core competencies of cookery?

The core competencies of cookery typically encompass a wide range of skills necessary for food preparation and service. Preparing sandwiches is a fundamental aspect as it involves various cooking techniques, nutrition knowledge, and food safety practices. It covers essential skills such as selecting ingredients, understanding flavor combinations, and proper handling of food items, which are crucial in the kitchen environment. Mastering sandwich preparation also lays the groundwork for understanding more complex dishes and presentations.

Beverage brewing, baking pastries, and grilling fish are specialized skills that may be important in various culinary contexts but are often considered secondary in relation to the broad foundational competencies in cookery. While all these activities contribute to a chef's overall skill set, sandwich preparation is highly practical and serves as a basis for further culinary techniques.
