Boniato (white sweet potato, Ipomoea batatas) is a staple root vegetable in Cuban cuisine. Using it in a dessert cake reflects the resourcefulness of Cuban home cooking — when wheat flour was scarce or expensive, root vegetables provided bulk and sweetness.
A dense, moist, pale brown slice of cake with visible boniato strands. The flavor is sweet, earthy, with a strong cinnamon presence. The texture is between a cake and a sweet potato casserole. Comforting.
Boniato's starches absorb moisture and provide structure (similar to how carrot cake uses grated carrots). The high water content of boniato makes the cake extremely moist. Cinnamon's cinnamaldehyde provides the warming aroma that is essential to Cuban sweets.
Variations
Some add raisins or coconut; the cinnamon amount varies; topped with meringue or cream.
