Authentic Southern Sweet Potato Pie vs Battenberg Cake

Both desserts share sugar, milk, vanilla, butter and eggs, yet use them very differently. In the sweet potato pie, mashed sweet potato is whisked with milk, eggs and melted butter into a smooth filling warmed by cinnamon and nutmeg, then baked in a pie crust until set. The Battenberg creams butter and sugar with eggs into light, springy sponges, one tinted pink, joined in a checkerboard with sieved apricot jam. Wrapped in marzipan, it offers soft cake, fruity jam and sweet marzipan rather than the pie's spiced, root-vegetable richness.
