The premise of Pomegranate Soup is like a well-known recipe. Take an insular village somewhere in northern Europe (here, Ireland). Invent some quirky inhabitants (quite a few here). Bring in an immigrant or two to found a restaurant or cafe (here, three sisters from Iran and an elderly Italian widow who had already been the outsider in a village for 40 years or more). Introduce the villagers to exotic cooking. They like it (a bit too fast here). Create some jealousy, greed, adolescent pranks, rivalry, and love interest (maybe a little contrived). Yup, yup, yup, a kind of a melodrama.
The portrayal of the sisters and how they fled the revolution in Iran is interesting and plausible. The portrayal of the Irish villagers and the Italian widow is pretty plausible too, at least at first. The events of the story start out not too bad. But as things progress, the story goes out of control -- spoiler coming.
The ending, where all the evildoers and mischief makers see the light, repent, and swear to be good, doesn't do much for me at all. Also, throughout the book the descriptions are often a bit over-written, sometimes with rather odd word choices that overreach to try to make it more vivid. In sum, it's a rather weak novel with really good food writing.
