Properly measuring flour is vital for success: fluff it with a fork, spoon it into the measuring cup, and then use a knife to level off the top.
When it comes to baking, I advise against making creative substitutions, as even small changes can ruin the bread and affect the outcome. To avoid any mishaps, please follow the recipe as written.
Important Note about Salt: Not all salts are made equal and cannot be substituted 1:1. If you are substituting table salt for kosher salt, you will need to cut the amount called for in the recipe by at least half.
