It is widely acknowledged that every time we eat, we employ the five basic senses of sight, hearing, taste, smell, and touch. We do this either consciously or subconsciously, and a combination of inputs from these five senses is what ultimately affects our perception of the food.
A good chef uses this knowledge to his advantage. Flaming dishes and sizzling platters have been accepted to be great merchandising tools in a restaurant. While a delicate balance of flavors is critical to the success of a dish, a variety of textures and temperatures also make a difference.
We may eat first with our eyes, but the nose is a close second. Our tongue can perceive only five basic tastes (sweet, sour, salty, bitter, and umami), so the multitudes of flavor that make up the profile of a certain ingredient are sensed by the olfactory nerves in the nose. Yes, we smell flavors; we don't taste them.
