The art of cooking is all about bringing ones individual talents to the kitchen. You must not only make the sauce but you must also feel the heart of the sauce. Be it on the prep table or on the stove or in the oven, you must have a sense of what you are in the process of cooking. Measuring cups will not tell you if you have added enough. Listen to your heart and feel like it is enough.
It is not only important to be a good cook or chef, it is equally important to be able to transfer ones culinary skills and abilities to someone who is willing to watch, listen and learn.
