Storage: Leftover cobbler is best served warm or at room temperature. Store covered in the refrigerator for up to 3 days. Reheat in the oven to restore crispness.
Substitutions: If you don't have heavy cream, you can use milk or buttermilk for brushing, though the flavor will be slightly less rich. For a vegan version, substitute the butter with cold vegan margarine and use plant-based milk.
Tips: Keep your butter very cold for the flakiest texture. If the dough becomes too sticky while rolling, dust with a little extra flour. If it cracks, simply press it back together; it will heal in the oven.
Variations: This dough works well for tarts or as a topping for savory dishes like chicken pot pie. You can also add a teaspoon of vanilla extract or lemon zest to the dough for extra flavor.
