While the pumpkin is baking, make the dough. For kneading the dough and filling the pie, I will use a food processor (blender, chopper). In a bowl, put everything at once: sugar; butter; flour; egg and water. I broke everything into crumbs. My hands are crumpled, the dough is wonderful and does not stick to my hands. Formed a tortilla and laid out in the form of D-18.5 cm. It's a one-time job and doesn't require any greasing. You can take any form and cover it with oil, if it requires it. Formed the sides with my hands (gave the appearance of a plate). Put in the refrigerator for 30 minutes.
