"Some things you know about, you know what the ingredients are - maybe not all of them. But it's up to you to put in the amount. It's up to the director to nag you until you get it right"

In this quote, Judi Dench is comparing the process of producing something to cooking. She recommends that there are certain things we recognize with and have knowledge about, but we might not understand all the information. However, it is our responsibility to determine the correct amount or combination of these components. This might refer to any imaginative venture, where we have to utilize our own judgment and skills to bring something to life. Dench likewise mentions the role of a director, who exists to guide and press us till we accomplish the wanted outcome. This quote highlights the value of both private effort and external assistance in the pursuit of excellence.
