How many inches should be left on either side of the score when preparing bread?

The correct answer indicates that 1.5 inches should be left on either side of the score when preparing bread. This measurement is significant because it allows enough space to maintain the structural integrity of the bread while also providing sufficient surface area for even cooking and proper crust development. Leaving 1.5 inches ensures that the bread does not become too thin at the scored area, which could lead to unintended tearing or difficulty in handling the bread. Additionally, this size helps to keep the proportion of the crust to the inside soft texture balanced, enhancing the overall quality of the sandwich.
