By the Book

When we say someone is doing something “by the book,” it means they are following the rules or guidelines precisely and strictly. It refers to adhering to established procedures or protocols without deviating or improvising. This idiom often implies a sense of thoroughness, precision, and a commitment to doing things the right way. It can be used in various contexts, such as in business, law enforcement, or even everyday situations.

Similarly, if a chef is preparing a recipe “by the book,” they are meticulously following the instructions and measurements to achieve the desired outcome. Doing something “by the book” can be seen as a sign of professionalism, integrity, and respect for established standards. It can also provide consistency and reliability in various fields. However, it’s worth noting that there may be situations where flexibility and creativity are necessary, and strictly following the rules may not always be the best approach.
