When you try new foods, or even indulge in old favorites, it's a good idea to cleanse your palate between courses. Think of your taste buds as delicate sensors that need to be recalibrated periodically. That rumaki appetizer (broiled, bacon wrapped chicken liver) tasted wonderful, but the lingering aftertaste could spoil the next course if you're not careful. Neutralize your palate for the delights to come by sucking on a lemon wedge or orange segment. Another option is to snack on a soda cracker or nibble a breadstick. If none of these palate cleansers are available, try sipping tepid water instead.
