I've always been interested on how to plan a progression of flavors through a meal. What makes a bad meal (from a flavor mix stand point) assuming all the component parts are well executed?
Should a meal, like a wine tasting, progress from white/light to red/heavy? Might you mix it up? Is the old "soup to nuts" progression still something to follow?
Should the same ethnic flavors or style of cooking be maintained through every course of a meal? Or might you change course when you change courses?
Are "palate cleansers" used to redirect the flavor of the meal or should they be used to complement what has been and what will be? Or are they "there" just because they're nice to have while the cook takes a breather?
How many flavors should be duplicated during the course of a meal and how many times (i.e. If ginger is in the main course, might or should it also be in the dessert and/or in the salad course and/or soup course?).
And of course, how many different flavors (meaning flavors of note, the stronger herbs and spices) should there be to keep the meal entertaining but not overwhelming?
