Describe how geogre made the irish stew.what was montmorency's contribution to it?

In Chapter Fourteen, George, Harris, and J. pass a number of landmarks near the idyllic villages of Wargrave and Shiplake. However, the day takes a turn for the worse when they attempt to peel potatoes for supper, but over-peel the potatoes until they are no bigger than peanuts. They attempt to make Irish stew anyway, putting in potatoes without peeling them. Montmorency catches a water-rat and offers it to the men to add to the stew, but they decline. The stew turns out to be delicious.
