The main ingredient in apple pie is, unsurprisingly, apples. Specifically, tart varieties like Granny Smith or tart-sweet options like Honeycrisp are often used to balance the sweetness of the sugar and the richness of the buttery crust. Apple pie is a classic dessert known for its flaky pastry crust filled with spiced, cooked apples, sugar, and sometimes a dash of lemon juice or cinnamon for added flavor. It holds a beloved place in American culture and is often associated with home baking and tradition, especially in autumn. Served warm with ice cream or whipped cream, it is a comforting treat.
