Nigella’s Lemon Polenta Cake

Nigella's Lemon Polenta Cake

Nigella Lemon Polenta Cake is a flourless-style cake made with ground almonds, fine polenta, butter, eggs, and fresh lemons. The polenta adds structure and a delicate grain, while the almonds bring richness. Once baked, the cake is soaked with a lemon syrup that seeps into the sponge, creating a moist, fragrant result that improves with time.
