There is an old saying: Garbage in, garbage out. It is a reference to the need for any creative, quality end product to start with quality, reproducible material. Imagine the Mona Lisa being painted with used motor oil and an old sponge. There’s a chance it wouldn’t be hanging in the Louvre, even if Da Vinci’s vision was that of the most beautiful woman in the world.
A similar saying exists in the culinary world—It helps to cook with the right ingredients. A nod not only to having a solid recipe, but also fresh, quality meats, fruit, vegetables, and spices. Many chefs would tell you it is the difference between your meal being received with a "fantastic!" or a "meh."
