YSK: the abolitionist history of pumpkin pie

YSK: there was a time when pumpkin pie was comparitively niche as fall holiday foods go. People would make sweet potatoe pie. However, it was essentially impossible to source sweet potatoes in the USA that were not made via slave labor, and so abolitionists pushed for an alternative: pumpkin pie. It's interesting what boycotts and politics are baked into culture (and ovens), and how we forget about their origins.
