Based on the book Fried Green Tomatoes at the Whistle Stop Cafe by Fannie Flagg (who has a cameo in the movie, and cowrote the script). Interestingly, the movie leads us to infer that Mary Stuart Masterson grows up to be Jessica Tandy (sorry to give away the ending, but I'm making a point). The book offers us two distinct characters with two distinct fates.

The book is fun.

In addition to the narrative, there are newspaper clippings and recipes, and the peripheral characters are given more life.
