Here's an effective way to enhance the taste of your cigar when you relight, even after several hours. Gently remove all the loose, gray ash from the foot of the cigar. With the cigar in hand, hold a flame 1/4 inch below the rim of the cigar. Rotate the cigar slowly until the periphery of the rim is lit. When the coal has spread over most of the foot, put the cigar in your mouth and hold a light to the end of the cigar until it ignites a yellow flame. DON'T DRAW ON THE CIGAR! Take a deep breath, and blow steadily and hard enough that the flame shoots out the end of the cigar. Leave the lighter in place, or remove it if the flame sustains itself. The flame should change colors ... quite amazing. Continue blowing for several seconds, until the flame changes from yellow to blue and gets smaller, perhaps extinguishing. Now take you first puff ... with all the tar and carbon burned off the foot of you cigar, it will no longer taste bitter!
