there is really no way to "season" a palate. Some people just genetically are unable to taste certain flavors even after smoking for years. Same with food and wine.. Your best bet IMO is to smoke anything you can get your hands on try things, smoke them slow and let the smoke stay in your mouth on different parts of your palate. Eventuallly smoke will taste like different things to you, and eventually you will be able to pick up subtle things on different parts of your palate.
