Final answer:
The dimension to flatten the BP dough halves is not specific, but typically it may be flattened to around ½-inch thickness. The length and width can be around 8 by 10 inches to allow cutting into 8 strips. However, this can vary depending on the recipe specifications.
Step-by-step explanation:
When preparing BP dough (presumably for breadsticks or similar twisted pastries) that needs to be cut into strips for twists and parm bites, the dimension to which you flatten the dough halves will vary based on the recipe or the desired thickness of the final product. However, a common dimension for such a purpose could be to flatten each half to a thickness of about ½-inch thickness, with a length and width that allows for 8 strips to be cut. For instance, you might flatten it out to a rectangle of approximately 8 inches by 10 inches, then cut each into 1-inch wide strips, but this is just an example and your specific recipe may call for different dimensions.
