Specifically, apple pie is the pick of an estimated 36 million Americans, according to the American Pie Council. The board offers a wealth of recipes, pie-making tips and ways to celebrate via its website, www.piecouncil.org.
Marie Callender's, a restaurant chain synonymous with pie, marks National Pie Day with specials. Its Perfect Pie Trio features chicken pot pie ($9.99) or Shepherd's pie ($11.99), accompanied by Caesar salad and a slice of (what else?) pie for dessert. (Cheesecakes, seasonal fresh fruit pies and promotional pies not included.)
If you miss Pie Day, don't worry. The offer is good through March 28.
Marie Callender's also has a new pie: Red Velvet Dream Pie. It's vanilla cream with layers of red velvet cake, topped by cream cheese icing. It's a good match for two holidays: National Pie Day and Valentine's Day.
The Red Velvet Dream Pie is $13.99 plus tin, available through Feb. 28. For locations, click on www.mariecallenders.com.
