Authentic Southern Sweet Potato Pie vs Traditional Welsh Cakes (Picau ar y Maen)

Both desserts lean on sugar, milk, butter and egg, yet they put them to very different work. In the sweet potato pie, melted butter, milk and two eggs are whisked into mashed sweet potato with cinnamon, nutmeg and vanilla, then baked in a crust until the smooth filling sets. The Welsh cakes instead rub cold butter into flour and bind it with just a little egg and milk, making a soft dough with currants and mixed spice that is cooked on a griddle until golden and slightly puffed, then dusted with sugar. The result is a smooth, warmly spiced baked filling on one side and small, buttery, currant-studded griddle cakes on the other.
