Plug in the cigar humidor and turn it on. Keep it closed and running for about 15 minutes before you begin.
Place two grams of unscented, unflavored tobacco in the glass dish.
Add about five drops of flavoring oil to the bowl of tobacco. Flavoring oils can be found in craft and hobby stores, as well as some specialty food stores. Flavor oils provide aromatic essences to the pipe tobacco while giving it a slight flavor. Flavor varieties include banana, chocolate, coconut and several others.
Toss the tobacco with the flavor oil lightly in the dish to mix it.
Place the dish containing the pipe tobacco into the cigar humidor. Close the lid and let the tobacco sit in it for about 30 minutes. The end result is a highly aromatic and flavorful pipe tobacco that can be enjoyed in your favorite pipe or hookah.
