In a world where carbs are increasingly shunned, people might think that the sweet potato would be particularly unhealthy. After all, the words “sweet” and “potato” hardly sound like markers of health. However, this assumption couldn’t be further from the truth. The sweet potato is only distantly related to russet potatoes and is a part of the morning glory family (they share a similar root structure). Orange sweet potatoes are high in the antioxidant beta carotene, which increases vitamin A levels in the blood. They are packed with B vitamins, potassium and vitamin C. Sweet potatoes are known to be high in fiber and have a low glycemic index, which results in a less immediate impact on blood glucose levels than a typical potato or starchy side dish.

Given the fact that sweet potatoes are healthy and easy to grow, they have been a source of sustenance in the United States for hundreds of years. Natives cultivated sweet potatoes in the Southern United States and Christopher Columbus brought them back with him on his return trip to Spain. Enslaved Africans also played a role in the proliferation of sweet potatoes in the U.S. 

A Little Sweet Potato History

Sweet potatoes are native to Central and South America and were first brought to Europe by Christopher Columbus in the 15th Century. They were cultivated by Native Americans prior to European arrival and bear a close resemblance to the African yam. A longtime staple of the West African diet, yams were easy to grow and naturally pest resistant, provided high yields and essential nutrients, and were consumed in a multitude of ways, including fresh, boiled, baked, cooked in ashes, dried and powdered.

Critical to survival for many, the yam is still revered at harvest festivals, called Yam feast days, throughout West Africa. A symbol of rebirth and renewal, yams are at the center of extensive mythology and often accompany ceremonies relating to birth, marriage, recovery from sickness or injury, and death.

When West Africans arrived as enslaved people in America, they applied their knowledge and experience cooking with yams to the American sweet potato, which quickly became a cornerstone of the Southern diet for all classes. Resembling the yam’s role in West Africa, sweet potatoes shielded Southerners against hunger during lean times and were especially vital for poor populations as they grow easily, produce abundantly (often with little human help), can be preserved through the winter in a mound of dirt and, when paired with greens, provide nearly all essential nutrients. 

The centrality of sweet potatoes in the Southern diet made sweet potato pie a core Southern tradition beginning in colonial days, when pies both stretched ingredients and turned humble meals elegant. Europeans, who had consumed pies since the Roman era, made pies in America using apples, lemons, plums and sweet potatoes by the late 1600s. Enslaved people from West Africa, who did the cooking in many colonial households, shaped sweet potato pie by experimenting with spices, techniques and various ingredients, adding cinnamon, nutmeg, vanilla, cloves, ginger, molasses, orange zest and coconut to the basic pie filling. Because pigs were abundant in the South, cooks used lard instead of butter in their pie crusts, giving them “a distinct, flaky quality.”

In the early decades of the twentieth century, George Washington Carver helped secure the longevity of sweet potato pie in Alabama. As the head of the agricultural department at Tuskegee Institute, Carver encouraged farmers to plant crops that would replenish the parched Alabama soil, including sweet potatoes. To spread his message, he produced scores of farming bulletins that were practical, free and comprehensible. Between 1898 and 1943, Carver issued nearly 50 bulletins on sweet potatoes alone, featuring the 118 products he invented from the sweet potato (including molasses, vinegar and shoe blacking) as well as various sweet potato recipes. His recipe for sweet potato pie, published in 1936, is a prototype of modern versions. 

In the 20th century, sweet potato pie became elemental to soul food. In reality, the dishes that comprise soul food are Southern dishes, consumed by Black and white alike for centuries. As culinary historian Frederick Douglass Opie notes, whether Black or white, “every poor person struggling to survive [in the South] ate soul food on a regular basis.”

But though the actual dishes may be identical, soul food separates itself from Southern food by underscoring its African American qualities. Black cooks were largely the ones to fuse African, Native and European traditions to create Southern food. Soul encompasses the ability of these cooks to transform ordinary ingredients, use whatever was at hand, follow the seasons and spice to perfection. Soul emphasizes the African cooking techniques, food pairings and seasonings that define Southern food. “It was simple food,” writes Opie, but “complex in its preparation.” And at the end of the meal, that last dish manages to roll all of those conflicting characteristics of soul – sweet, savory, complicated, straightforward, tenacious, joyful, sustaining, luxurious – into one: sweet potato pie.
