It is a savory or sweet pie filled with a mixture of sweet and tart apples, sugar, cinnamon, and butter, all wrapped in a puff pastry or brisée crust.The preparation of Irish apple pie involves peeling and thinly slicing the apples, then seasoning them with sugar, cinnamon, and butter, and cooking them in a pot until they become soft and caramelized. The apple mixture is then placed inside a puff pastry or brisée dough shell and baked in the oven until the crust turns golden and crisp.Irish apple pie is a popular dish in Ireland and is often served during holidays such as St. Patrick's Day or Thanksgiving. The pie is often associated with Irish culinary tradition, but it is made in many variations around the world, with the addition of ingredients such as cream, nutmeg, lemon, and vanilla.The history of the Irish apple pie dates back to at least the 18th century, when apples were a very common ingredient in Irish kitchens.
