Szarlotka is a traditional apple pie that is hugely popular in all of Poland. There are countless ways of making it, but typically, it's made with shortcrust pastry or semi-shortcrust pastry and cooked or raw apples. It's a double-crust pie, and the top of the pie is usually crumbled.
However, there is one variation of szarlotka that is well-known, and that is one that also includes a meringue layer underneath the crumble topping. Szarlotka can also have other fruits like peaches and pears, the apple filling can have raisins, and the crumble topping can be mixed with almonds.
