We always used Kellogg's Croutettes for Thanksgiving/Christmas dressing, and the seasoning was perfect. A few years before it was discontinued, I noticed that it would show up in a special display around holiday time, and knew I had to pick it up, as it would sell out quickly.
Luckily, I'd written down the exact amounts of everything I used with the croutettes, but getting the perfectly-seasoned (to my liking, anyway) croutons was an effort. Many of them were good, but just not the same. After a few years, I finally found one that's similar enough to do the trick, but I still miss the old standby.
Have you tended to use your tried-and-true recipe for stuffing, or do you change from year to year?
