Dutch apple pie has a buttery and sweet streusel topping, aka crumble. Cream is often added to the apple filling for a richer texture. French apple pie has been referred to synonymously with the Dutch version. However, traditional French apple pie or tarte tatin is sweetened apple slices cooked in a skillet, then topped and baked with a crust-like pastry. It's flipped over with the fruit exposed for a stunning upside-down effect.
