What is a skewer primarily used for in food preparation?

A skewer is primarily used to secure food together during cooking, making option B the most appropriate choice. Skewers are often employed to hold pieces of meat, vegetables, fruits, or a combination of these foods, allowing them to cook evenly and consistently over a heat source. When grilling or roasting, skewers ensure that the food remains in place, promoting even cooking and easier handling.

The other options do not accurately represent the primary function of a skewer. Measuring ingredients accurately pertains to the use of measuring cups or spoons, which are designed specifically for that purpose. Flavoring food while cooking typically involves spices, marinades, or seasonings, rather than a skewer itself, even though skewers can hold flavored items. Decorating dishes before serving generally involves presentation techniques such as garnishing or plating, which has no direct relation to the skewering function. Thus, the use of a skewer is tightly focused on the aspect of securing food for cooking.
