Preheat oven to 350°F. Puree sweet potato in food processor until smooth. Add sugar, butter, House-Autry Buttermilk Biscuit Mix, evaporated milk, eggs, vanilla, nutmeg, allspice and salt; blend well. Pour into a buttered 2-quart casserole dish. Cook 50 minutes, or until filling is slightly puffed and center barely jiggles when shaken.
Praline Topping: Combine pecans, brown sugar, corn syrup, vanilla and a pinch of salt, mixing well to ensure pecans are well coated. Scatter evenly over cooked casserole; bake for 10 minutes, or until topping is bubbling around the edges. Serve at room temperature; store leftovers in refrigerator.
