Banana Pudding is popular in north Alabama, or as it is called 'nanner puddin'. Sugar overload with some banana slices, but damned good.
Growing up in the Hudson Valley of NY it was all about the apples for dessert. Lots of apple orchards. Apple pie, using Macintosh apples was locally popular, and this is contrary to many recipes one can find. And please, no cheddar cheese with the pie. Either by itself or with vanilla ice cream.
