I’ll admit sweet potato casserole often tastes more like a dessert than a side at Thanksgiving, but I couldn’t resist using the syrup from canned sweet potatoes to add some fall vibes to a fun Thanksgiving cocktail. Topping this sweet potato cocktail with torched marshmallows may be a bit over the top, but I’d imagine that’s what Aunt Vernie would do. I use allspice dram for that tropical hit of allspice, clove, and pepper flavors, but a spiced rum is a fine substitute.
