What does the term "blend" mean in cooking?

In cooking, "blend" refers to the process of mixing two or more ingredients thoroughly until they are combined into a uniform mixture. This technique is commonly used to ensure that flavors and textures are evenly distributed throughout a dish. For instance, when blending batters for baked goods or mixing dressings, achieving a consistent mixture is crucial for the final outcome of the recipe. The goal is to integrate the ingredients so that they become part of a cohesive whole, which enhances both taste and presentation.

The other choices focus on different cooking techniques that do not align with the definition of "blend." Heating ingredients separately does not involve combination, while serving hot or chilling ingredients pertains to temperature and presentation rather than mixing. This distinction helps clarify why the correct interpretation of "blend" specifically emphasizes thorough mixing.
