To make this recipe gluten-free, substitute both pie crusts with a gluten-free pie crust alternative. Many store-bought gluten-free crusts are available, or you may prepare your own using a gluten-free flour blend. Handle gluten-free dough carefully, as it tends to be more delicate and prone to cracking. Ensure all other ingredients used (such as cornstarch) are certified gluten-free to avoid cross-contamination.
