Tips

  • Thanksgiving favorites: pumpkin, apple and pecan. With three kinds for 20 guests, bake or buy two of the most popular and one of the others.
  • Pumpkin and pecan pies must be refrigerated and keep 3–4 days. Fruit pies are fine on the counter for 2 days.
  • Pies freeze well: baked pumpkin pie keeps 1–2 months. See the leftovers chart.
