Diners who frequent higher end restaurants may have no problem accepting a chef's use of unusual or artificial flavoring agents when they are used to bring out unusual sensations in the food, like the menthol crystals used by Wylie Dufresne in some dishes at wd-50. The same cannot be said when artificial flavorings are used instead of readily available ingredients.
Leading French chefs Joel Robuchon and Alain Passard have denounced the growing trend among French cooks for using non-natural ingredients in their cooking, like saffron perfume, truffle essence or powdered wine sauce. The objective, unlike the use of similar things in the conceptual molecular gastronomy model, is to be able to achieve cheap, quick results. French cooks who use them use the "ingredients" secretly, for fear of being accused of cheating by others in their profession. A supplier stands by the products, saying "An increased range [of flavors] should logically be tolerated and accepted by everyone in the end," while Passard said "I don't know what to call the people who use these chemicals, but they are not cooks."
