Sweet Potatoes

Topping

⅔ cup all-purpose flour ⅓ cup packed light brown sugar ¼ teaspoon table salt ⅛ teaspoon cayenne pepper 4 tablespoons unsalted butter, melted

Why This Recipe Works

Inspired by a family recipe, we were after a creamy sweet potato casserole topped with a crunchy, salty-sweet topping. Roasting the sweet potatoes rather than boiling or steaming them concentrated their sweet potato flavor. A splash of orange liqueur and a little brown sugar made them holiday-worthy. A simple stir-together streusel made with flour, brown sugar, salt, and melted butter tasted great and provided a contrasting crunch on top of the creamy sweet potatoes. A pinch of cayenne added to the topping carried a hint of heat.
