Here's a thing, or so... I've been eating mayonnaise that has 'best if used before 19 April, 2006' on the side. That's almost a year ago. I can't tell a difference in the taste, though. It DOES seem to take me forever to eat a thing of mayonnaise.... -- Felix J. McGillicuddy ME-->GA '98 "Your Move" ALT '03 KT '03 http://Felixhikes.tripod.com/
