Claire Saffitz and Brad Leone know that after turkey and stuffing, a Thanksgiving meal is judged on its pies. Guests, all of whom have saved room in their stomachs, will ask: 'What type of pies did the hosts provide? What was the quality of the crust? Was this pumpkin pie pumpkin-y enough?' Claire and Brad want you to pass your guests' pie grading, so they've endeavored to make the perfect Thanksgiving pie.
