Authentic Southern Sweet Potato Pie vs Eierkuchen (German Pancakes)

Both desserts rely on sugar, milk, butter and eggs, but put them to very different work. In the sweet potato pie, they are whisked into mashed sweet potato with cinnamon, nutmeg and vanilla, then baked in a crust until the eggs set the filling into a smooth, spiced slice. The Eierkuchen turns them into a thin, lightly sweetened flour batter, fried in butter until golden with slightly crisp edges, leaving most of the sweetness to toppings like jam or extra sugar. One is dense and rich; the other is thin, tender and best eaten warm from the pan.
