For example, basic balsamic vinegar is slightly acidic and best used for salad dressings.

The next grade up is significantly smoother, and should be used for finishing and for marinades.

Trade up one more step and the balsamic has a well rounded, full-bodied flavor, ideal to make warm sauces over meats and fish.

The top grade, made from the the best reserves, should itself be reserved to glorify a simple dessert like fresh fruit and ice cream, or a wedge of Parmigiano-Reggiano.

Follow the same steps with olive oil: regular for cooking, extra-virgin for dressing salads and garnishing other foods.
