Being out of work and broke, I've been dipping into the food reserves quite heavily. Tonight I came across two large cans of Campbells New England Clam Chowder with a "use by" date of Aug '06 - almost exactly 1 year too old. So here we go, I'm puttin' my gastrointestinal tract on the line in the name of shelf life research. It smelled ok, but it looked a little...... hmmm.... more congealed than usual. Tasted fine. I microwaved it and ate it about 10 minutes ago and so far so good. We'll see how this turns out in the next few hours I'm sure. 11:40 pm - No adverse affects noticed.
