Aside from the obvious major ingredient, apple pies can have a great deal of variation. Some recipes incorporate spices such as cinnamon and nutmeg, they typically include sugar, and some recipes also use dried fruit (currants or sultanas). A delicious variation on the apple pie uses fresh or frozen blackberry.
The fruit for the pie can be fresh, canned, or reconstituted from dried apples. This affects the final texture, and the length of cooking time required, but it has no effect on the flavour of the pie. Dried or preserved apples were originally substituted at times when fresh fruit was unavailable.
Apple pie is traditionally associated with America, where it is a highly popular dessert, often served with a scoop of vanilla ice cream. This is known as 'apple pie a la mode'... 'As American as apple pie' is a common saying due to this association.
