Also known as Dutch apple pie, the best crumb pie starts with the apples: we always suggest a mix of different tastes and textures for a balanced filling that is both sweet and tart with toothsome and soft pieces. For example, Granny Smith apples are tart, Golden Delicious hold their shape nicely and McIntosh add an applesauce-like quality – a mix of these and/or your favorite varieties are ideal. For a simple upgrade, toss the filling with a couple tablespoons of heavy or sour cream for added richness. The pie dough gets special attention too: a preheated baking sheet acts as an extra heat conductor and sets the bottom crust before it has a chance to become soggy. Keep an eye on the crumb topping and cover with foil if it browns too quickly.
Using a mix of apple varieties (tart like Granny Smith, firm like Golden Delicious, soft like McIntosh) creates a more complex and interesting filling texture and flavor. Ensure all pie dough ingredients are very cold for a flaky crust. The technique of preheating a baking sheet on the lowest rack is crucial for achieving a crisp bottom crust. Monitor the crumb topping during the longer bake time and loosely tent with foil if it begins to brown too quickly to prevent burning. For extra richness, consider tossing the apple filling with a tablespoon or two of heavy cream before baking.
