The increasing "use fresh herbs" mantra, especially with TV chefs, is silly because it pushes people in one direction without explaining subtleties. Certain herbs (as people have been noting above) are only potent or useful when dried. There has always been a place for the use of dried herbs. Try using fresh basil in a dish which needs the darker flavour of dried basil to permeate it over extended cooking... the fresh basil fades away in comparison (and tastes quite different anyway). That said, many many herbs are much better fresh (rosemary, laurel/bay), and some are almost useless dried (curry leaves, borage?). --lamington
