There is a thread somewhere on here about "Palatable frozen foods", which brings me to a recent experience I had. A couple of weeks ago I opened my freezer to find a box of Ellio's pizza. I really had no interest in Ellio's pizza, but for whatever reason I took out one rectangle sheet of the frozen pizza and placed it in the oven @ 350 for the 10-12 minutes.
I took it out of the oven, took one bite and was immediately brought back to grammar school days. At my grammar school we only had "Hot Lunch" once a week, and once a month that "Hot Lunch" was Ellios Pizza. Immediately my taste buds brought me back to the Church Cafeteria....the smell, the sounds of kids screaming around me, the simple taste of that forzen Ellios Pizza brought back such a rush of memories.
How about the rest of my fellow hounds? Is there something you can eat that takes you immediately back to a special time or place?
