I Swear By This One Ingredient to Make the Best Sweet Potato Casserole

It's that time of year when the bright-flavored light meals of summer morph into the more autumnal tastes that will grace our tables during the coming months. The taste spectrum cycles from the vine-ripe tomatoes, bitey chiles and sweet corn to those of Brussel sprouts, cabbages, root vegetables and, dare I say it, pumpkin spices. It's time to bring out those roasting pans and casserole dishes.

In her book Ham Biscuits, Hostess Gowns, and Other Southern Specialties, the late Julia Reed devoted an entire chapter to the Southern love of casseroles. While the green bean one that often turns up at funeral repasts, usually topped with canned fried onions, was never a part of my experience, I was tickled to learn that we shared a love of sweet potato ones. I grew up eating a candied sweet potato casserole—that we mistakenly called candied yams—every year with the Thanksgiving turkey. (Enslaved Africans who were brought to North America missed the yams they were familiar with. In the New World, they saw sweet potato as a close substitute and called them yams, thereby creating a linguistic confusion that lasts until this day.)

The casserole came to the table piping hot in a Pyrex dish that had its own holder for table use. That was so long ago that the Pyrex dish would now be revered as mid-century modern. The casserole was topped with gooey melted marshmallows. While I loved them then, now, like my friend, Julia, I feel that the marshmallows are overkill that should probably stop after diners leave the kiddie table.

Many more-adult versions of this classic casserole swap out the marshmallows for some form of pecan, either layered or mixed into a topping. However, I'm a quirky eater who doesn't like the texture of nuts in my food, and I don't want to spend the meal picking pieces of pecan out of my sweet potatoes, even if they're toasted in butter beforehand! Up until recently, it's been, "Give me plain sweet potatoes—that's enough!"

Then a friend introduced me to a pecan liqueur called Rivulet. It was a revelation.

The liqueur, a brandy infused with the distinctive taste of roasted pecans, gave me the hint of toasted pecan flavor that I liked without those pesky nut pieces sticking in my teeth. It was the perfect addition to what I'm now calling my "Purist's Simple Sweet Potato Casserole."
