Why are the most exquisite drinks and delicate flavored dishes served at the beginning of a meal or separately?

Our tongue helps us to feel the finest facets of taste. We distinguish between different flavors of a wide variety of dishes. Meat and strawberry do not taste the same to us. If a restaurant serves us exquisite food and drinks, then they do it at the beginning of the meal so that our receptors fully feel the subtle notes of the dish. If you eat a piece of sausage before a meal, and then supplement your meal with a piece of exquisite French cake, then you won’t be able to enjoy the dessert. The taste of the sausage will overwhelm the taste of the sweet treat.
