We bake richer quality plum cakes and are still improving and experimenting with different methods from time to time. A plum cakes a very rich combination of many dry fruits, egg, flour, and butter. A well-prepared plum cake has a longer shelf life and its taste, flavor, and texture improve and nurture better with a longer period. This is the reason why since its inception in 1883, the plum cake is still one of the most popular cakes sold all over the world.
