Even beloved food holidays like Halloween and Thanksgiving can be filled with polarizing provisions. For instance, at a pumpkin pie recipe share, I couldn't resist telling others the story of how 30 years ago, my immigrant mother — perhaps the world's greatest pumpkin pie opposer — forced down a slice of pie by washing down every bite with water, so as not to seem ungracious at her first Thanksgiving dinner. Have you ever eaten something horrible just to avoid offending a host?
