What method is used to create cookies with multicolored patterns like checkered boards?

The icebox method is the correct approach for creating cookies with multicolored patterns, such as checkered boards. This technique involves preparing a dough that can be chilled and shaped before baking.

In the icebox method, the cookie dough is typically formed into logs, which are then chilled until firm. This allows the dough to be sliced easily into even pieces, maintaining the distinct pattern, like alternating colors in a checkered design. Once the dough is chilled, it is critical to slice it precisely to reveal the colorful pattern, making it ideal for designs where visual appeal is key.

The other methods mentioned, while useful for various types of cookies, do not provide the same control over the appearance and integrity of a pattern. The drop method involves spooning out the dough onto a baking sheet, the rolling method typically involves rolling out a single color of dough and cutting shapes, and the piping method focuses on shaping dough into designs directly onto the baking sheet by using a piping bag. None of these techniques would yield the multicolored, structured appearance that the icebox method achieves.
